Thanks, Kenny. Our foundation of loyal members and our well recognized and admired brands, provide a key point of competitive differentiation for Wheels Up. As Kenny mentioned earlier, our focus is now on how we can continue to serve our customers and deliver exceptional experiences at scale, but do so profitably. Our headcount reduction announcement last week was the culmination of a thorough and difficult review over the past several months to scrutinize and prioritize our spending profile across technology, sales and corporate overhead. The expected $30 million of annualized savings from this effort is a meaningful step forward, and we are continuing to work to further streamline our cost profile, and accelerate the pace of operational improvement. As I walked through my prepared remarks, I will touch on our fourth quarter highlights, along with an update on our operating initiatives and how you should model the company going forward. Kenny touched on our total revenue performance. So let me run through the components. Membership revenue was up 13% year-over-year. That growth rate has moderated in recent quarters, reflecting some macro headwinds and a recent shift to more connect members, as we are increasing the mix of on-demand charter flying to balance out our network. We have also focused our sales and marketing spending to target more profitable revenue that leverages network density in specific regions and at specific times. Flight revenue was up 9% year-over-year and higher than expected. The increase was due to a 14% year-over-year increase in flight revenue per live leg, offset by a 5% decline in live flight legs. Without Air Partner, which reports on a net revenue basis, flight revenue per live flight leg was up 19% year-over-year. Aircraft management revenue was $62 million in the quarter, continuing to hover in the $60 million per quarter range, reflecting steady management fees and regular uses of the aircraft by their owners. Other revenue was $50 million, up significantly year-over-year due to the addition of Air Partner and an increase in aircraft sales. Our adjusted contribution margin was 4.7% for the fourth quarter, down slightly sequentially, but at the high end of our guidance of 4.25% to 4.75%. Excluding Air Partner and aircraft sales, our core Wheels Up adjusted contribution margin was up sequentially, reflecting continued progress on our profitability initiatives, including higher utility and margins for our 3P flying. Turning to operating expenses. For the quarter, sales and marketing expenses were 6.4% of revenue, down sequentially in dollars and as a percentage of revenue, primarily due to lower commissions related to aircraft sales. Technology and development expenses were 3.2% of revenue in the quarter, with total dollars down 18% sequentially as we completed several IT projects from outside vendors but up 42% year-over-year as we continue to invest in technology to support our marketplace and efficiency efforts. General and administrative expenses were 5.9% of revenue and flat sequentially in dollar terms, as cost-cutting initiatives were offset by an increase in bad debt reserves. Overall, OpEx was down $5 million sequentially in the quarter, in line with our guidance and consistent with our cost reduction efforts that support our path to positive adjusted EBITDA in 2024. Adjusted EBITDA was negative $43.7 million for the quarter, coming within our negative $40 million to $45 million guidance range. Excluded from that amount are one-time non-cash charges associated with the impairment of goodwill, primarily as a result of an increasing discount rate as well as certain historical receivables. Capital expenditures were $12.7 million in the quarter, including capitalized software of $9.2 million. For the year, capital expenditures were $111 million, coming in below our prior guidance. Excluding the purchase of tech strong aircraft that were previously leased, capitalized software was roughly half of our normal capital spending, reflective of our continuing technology investment. We ended the quarter with $586 million of cash and cash equivalents on our balance sheet, up from $285 million in the third quarter reflective of the October debt financing and higher prepaid block sales. On the first call after I joined last summer, we as a management team, put a stake in the ground and committed the company to a goal of achieving positive adjusted EBITDA in 2024. On each earnings call since then, I have provided additional context to show the progress we are making. For today, I will provide more details that will highlight how we are on the right path for the long-term success of the company. As we have previously stated, there are three key components to achieving positive adjusted EBITDA in 2024; cost reductions, pricing initiatives and program changes and operational efficiency. I will start with our cost reduction efforts, which primarily relates to our OpEx. As we said previously, we expect to manage our OpEx down to the low double-digit level as a percent of revenue in 2024 versus a peak of just over 16% in the third quarter of 2022. Last week's plan to reduce headcount costs by $30 million annually is one part of our plan to streamline our business. As I touched on earlier, we are prioritizing our sales and marketing efforts to drive specific demand that augments our network density where incremental margins are highest. We will continue to strategically invest in our brand but have significantly scaled back the spend that some of our hallmark events that we have sponsored in the past. Turning to technology and development. While we are still investing in our marketplace, we have prioritized our investment on delivering new features that we believe are margin-enhancing by directly improving and automating key processes that are highly manual today. Let me give you two quick examples of what we have already accomplished. The first is that we increased the level of automation in our billing function that enhances accuracy and timeliness of customer invoices and increases the productivity of our back-office teams. The second is that we have now deployed enhanced cross fleet and cross certificate, scheduling optimization capability that helps us better match our demand to our available capacity to improve our scheduling efficiency, customer service and contribution margin. Going forward, we have a lot of opportunities to digitize more aspects of our business to reduce manual back-office processes. Those efforts are focused on continuing to improve the scheduling and operations of our fleet and enhancing the Wheels Up mobile app and other booking channels to sharpen our ability to target profitable demand through dynamic pricing in specific regions, days and times. Rounding out OpEx, we know we need to be much leaner on our general and administrative expenses, and we expect to see significant progress on those expenses in the second quarter and over the balance of the year, as we recognize the impact of our recently announced cost reductions. To put it all in perspective, we expect a modest sequential decline in OpEx in the first quarter with a more meaningful step down in the second quarter as the next big leg of our cost-saving measures I've touched on take hold. More important, we expect to end this year with OpEx down to the low teens as a percent of revenue. That equates to over $50 million of expected annualized savings, a 20% reduction versus the third quarter of 2022, which was a high mark for us. We believe the progress we will show this year will put us well on track of our goal for low double-digit OpEx as a percent of revenue in 2024. The next two components of our path to a positive adjusted EBITDA pertain to our adjusted contribution margin. Pricing initiatives and program changes are tools that we are increasingly using to improve our asset utilization. Our goal is to be more selective on our growth going forward. We know that where we have density, we have a cost advantage. As I touched on, we are focusing our business to dynamically price targeted flying in specific regions on off-peak days and times where we have capacity and network density. One example is a special offer for travel on our keen airs east of the Mississippi. That targeting -- targeted flying comes with lower repositioning and higher fixed cost leverage and incremental margins along with better flexibility and service for our customers. Early customer feedback has been encouraging, leading to improving utilization and efficiency on keen airs and we see opportunities for similar offers and program changes with all of our cabin classes. Meanwhile, we have taken steps to reduce some of the less desirable regions from our guaranteed programs where many flights are associated with costly repositioning legs, which can result in much lower margins. Previously enacted pricing increases will continue to flow through our book of revenue. However, looking over the course of the year, we expect flight revenue per live flight leg growth will moderate, primarily due to a higher mix of off-peak dynamically priced line. However, we expect the changing mix of revenue will be accretive to adjusted contribution margin as we better leverage our fixed costs and drive efficiency across our network. Let me now turn to our initiatives that will drive operational efficiencies. We are establishing specific fleet performance teams who have dedicated P&L and are empowered to make decisions on a more granular level that optimizes the performance of each aircraft type. We now more closely track key metrics such as pilot staffing, maintenance availability, spare part levels and demand allocation on a fleet-by-fleet basis with a focus on differentiating strategies to drive the best results possible. We are continuing to overhaul our internal and external maintenance operations to improve aircraft availability. We have further strengthened our preventative maintenance program, so that our aircraft will have greater operational readiness, especially during peak times. And we are adding additional internal labor capacity, while consolidating and restructuring agreements with third-party providers to reduce cost and aircraft out of service times. We anticipate these and other improvements will increase our fleet availability by nearly 10% in 2023. A well-functioning maintenance operation support tire utility of our aircraft and significantly reduces the need for expensive recovery flights, which can negatively impact member experiences and our financials. We are taking a hard look at our fixed cost. As we increase network density, we will reduce repositioning legs, which effectively frees up capacity. That presents us with the option to reduce our fixed asset base, which in turn will lower our fixed costs and drive higher utilization on our remaining fleet. Our asset-right fleet allows us to augment the capacity of our 1P controlled fleet with third-party providers. When there was a capacity shortfall in the industry, we had signed a number of fixed price agreements to guarantee a minimum level of 3P capacity during 2022. Our customers appreciated that effort and continue to reward us with their loyalty. However, today in a more balanced market, we are adjusting and renewing contracts at reduced rates with shorter commitment, which improves margins. We are also working diligently to reduce the complexity in our business. At mid-year, our new state-of-the-art member operations center will consolidate multiple facilities from around the country in Atlanta, one of the world's largest aviation hubs and the location of our partners at Delta. That will improve our customer service through better automation, increase the productivity of our employees and accelerate our response times for unanticipated travel interruptions, which will reduce our recovery expense. We expect the consolidation of our FAA operating certificates will simplify our flight operations by harmonizing our procedures across the entire company versus the multiple operating silos that exist today. We recently completed an important milestone with the Alante certificate by consolidating those operations and all of our CJ3 Aircraft onto one certificate. That move along with further certificate and operational harmonization actions we are taking will contribute meaningfully to the improvement we were expecting in our adjusted contribution margins and our service delivery. In summary, we expect to end this year with a high single-digit adjusted contribution margin. We already have good visibility to achieving that as recent actions we have taken represent almost half of that expected improvement, which will start to be realized in the second quarter. We will provide an update on additional actions when we report our first quarter results in a couple of months. We believe all of these actions will set us well on our path to achieve mid-teens adjusted contribution margin in 2024. So with that, let me turn to our guidance. Due to the macroeconomic uncertainties and our own more targeted focus, we expect first quarter revenue will increase mid single-digits year-over-year. January is historically a more volatile month due to the variation in personal and family travel over the holiday period, and the macroeconomic environment made this even more challenging, resulting in a slower start than we anticipated. However, we saw a steady improvement in the back half of February and March booking activity is up significantly versus prior months, which gives us confidence heading into Q2. For the year, we expect sequential growth over the course of the year with revenue expected to come in at a range of $1.55 billion to $1.6 billion, reflecting macro uncertainties and our focus on profitable revenue that leverages the density of our network. We expect first quarter adjusted contribution margin will fall in the 3.5% to 4% range. That is down from what we reported in the fourth quarter, partially driven by the seasonal drop in revenue, which masks significant progress we have made to reduce our fixed cost and improve our operating efficiencies. To underscore that point, with seasonally stronger revenue in the second quarter, we expect adjusted contribution margin will come in at the highest level the company has posted in almost two years. With continued sequential revenue growth, we expect to exit the year with high single-digit adjusted contribution margins, averaging 6.5% to 7.5% for the year. As I mentioned earlier, we expect OpEx dollars will be roughly flat sequentially in the first quarter, with a step down in the second quarter from a full three months of our recent cost initiatives. We expect OpEx will end the year at low-teens as a percent of revenue, which is significant progress from the high watermark in 3Q 2022. We expect first quarter adjusted EBITDA loss to be in the range of $45 million to $50 million, reflective of the sequential decline in revenue. Going through the metrics, I just laid out, we expected – we expect an adjusted EBITDA loss of $110 million to $130 million for the full year. We expect to report a GAAP net loss of between $95 million and $105 million for the first quarter, and we expect our GAAP net loss for the year to come in the range of $300 million to $320 million. We expect capital spending for 2023 will be in line with what we have outlined as normal capital spending in the mid-single-digit range of revenue going forward. As detailed on this call, we are making the hard decisions required to position the company for long-term success. It is very important to me that we deliver on our commitment. I'm proud of the company's ability to demonstrate it can hit its targets over the last several quarters. While we still have work to do, I am confident in the goals we laid out for this year, and I hope it gives you confidence that we have a credible plan to achieve positive adjusted EBITDA in 2024. With that, let me turn it back to Kenny for some concluding remarks, before we open the call for Q&A.
