Thank you, Vinayak. As Kenny noted, we are very pleased with our strong revenue growth this year with third quarter revenue up 55% year-over-year to $302 million. This reflects the unprecedented demand we are experiencing as well as the success of our membership programs and our broad-based delivery capability. Let me start by providing more details about our revenue, which is broken down across 4 main categories: membership, flight, aircraft management and others. Membership revenue grew 35% year-over-year in the quarter. We believe membership revenue is highly visible and largely recurrent. Given our 80% retention rate for Core and Business members generally and approximately 90% of those Core and Business members that purchase blocks. In the third quarter, we added 860 net new members with active members growing 45% year-over-year. We were very pleased to have crossed 11,000 member thresholds, finishing the quarter with 11,375 Active Members. Our Core and Business offerings with their guaranteed availability and cap rates across all asset classes, continue to resonate with the market, particularly as market pricing increased. That was a key driver of growth in the quarter, along with the initial success of our AmEx partnership that Kenny commented on earlier. Kenny and Vinayak touched on the recent changes to our programs. We will essentially be managing near-term membership growth based on our expected ability to deliver. We believe this will be temporary, however, as we execute on our plan to increase our delivery capabilities. Turning to flight revenue. Flight revenue was up 3% sequentially this quarter and up 56% year-over-year. We think the best way to model flight revenue is to multiply Live Flight Legs by Revenue per Live Legs. Live Flight Legs were up 8% sequentially from the second quarter and up 52% year-over-year. We continue to see strong leisure demand and the beginning of a pickup in business in international travel. We also believe there was significant demand from connect nonmembers which we simply could not address during the quarter given the supply constraints. Flight revenue per Live Flight Legs was almost $11,100 for the quarter, up 2% year-over-year and down 5% sequentially, reflecting a higher mix of shorter haul trips on smaller aircraft. This is normal seasonality for the third quarter. Prepaid blocks, which provides visibility into our future flight revenue were $172 million in the quarter, up 120% year-over-year. We expect fourth quarter block sales to be very strong as well and outpace third quarter block sales. That said, please note that the fourth quarter of 2020 was a particularly strong quarter for block sales due to the resumption of the federal excise tax on flight at the beginning of 2021. This pulled forward lost demand into the fourth quarter of 2020. As I mentioned earlier, Core and Business members who buy prepaid blocks typically renew at around 90%. Now approximately 60% of our Core and Business members have a block, up from roughly 50% a year ago. Members who are buying block today are generally able to lock in current cap rates for the duration of their prepaid blocks. Effective December 1, we are implementing a cap rate increase of 8% to 13% on the cabin classes that are most constrained, [indiscernible] and Light Jets. New and existing members are able to purchase at the old rates and program term through the end of November. Historically, we've raised rates and changed program terms as of January 1 of each year. So this year has changed the month earlier than normal. Switching to aircraft management. Our aircraft management revenue grew 51% year-over-year in the quarter due to a higher mix of pass-through revenue, reflecting higher owner usage of aircraft. We were managing approximately 160 aircraft as of the end of the third quarter, which is down slightly from the prior quarter. As we mentioned during our second quarter call, we are continuing to call legacy management contracts that are not commercially advantageous to us. There are about 20 of those contracts remaining to be worked through. On a positive note, managed charter hours, hours that our members fly on our managed tails were up approximately 40% year-to-date, even on that slightly smaller fleet. We believe that aircraft owners are recognizing how our strong demand generation helps them to monetize their underutilized aircraft. We are encouraged by our healthy sales pipeline for new managed aircraft. We are also actively working on a new product initiative to further highlight our value proposition for aircraft owners. Once we work through the reduction of sales I mentioned, we expect that total aircraft under management will resume growth in 2022. Charter friendly managed aircraft are an increasingly important source of supply for us as it allows us to flex up our capacity at prenegotiated rate. Our other revenue is a small percentage of our total revenue and represents revenue earned from software, fixed-based operations, or FBO, maintenance, aircraft sales and special missions, including defense. Now let me address cost of revenue and margins. Our strategy is to optimize utility and efficiency across all fleets. In essence, to use the right plane in the right place at the right time to minimize repositioning legs and improve profitability. To manage the third-party asset light tail is closest to our customer, we will try to utilize the better positioned aircraft. We are going to enable this through the process improvements, technology and automation initiatives that Vinayak described as well as through improved operational and maintenance capabilities. That's how we expect to drive significant margins in the future. In the second quarter of this year, we are much better able to balance our service commitments with our costs, and our contribution margin improved steadily each month during the quarter. However, that trend reversed in the third quarter as higher demand in industry labor, supply and cost pressures compounded. That led to significant margin declines in August and September, which were well beyond expectations. As a result, adjusted contribution margin fell to 6.3% in the third quarter, down from 10.7% in the second quarter. We are now showing contribution and contribution margin on an adjusted basis to exclude equity-based compensation and exclude certain other items that are not indicative of our ongoing operating performance. Prior to us issuing a unique broad-based equity grant for our pilots, the amount of equity-based compensation included in cost of revenue was not significant. We believe that the adjusted contribution calculation conforms more closely to our adjusted EBITDA calculation. We and the aviation industry at large are not immune to the cost pressures and supply constraints impacting most companies across the global economy. Labor and part availability and costs, commodity prices, shipping, fuel and travel costs have all gone up and/or tightened across the Board. The largest impact in the quarter was pilot availability, driven by increased competition for experienced pilots. Additionally, maintenance parts and labor constraints resulted in longer return to service time. Combined, these factors led to a significant sequential reduction in our on-fleet utility as we couldn't fly all the aircraft we had available on certain days. As a result, we are forced to rely more on our 2P and 3P fleets. At the same time, some third-party operators with capacity in the spot market took advantage of the limited supply and raised their wholesale pricing, upwards of 20% or more. Related to that, we experienced a significant increase in expensive cabin class upgrades as light jets were particularly supply constrained. Again, we absorbed those costs and upgrades as we focused on delivering for our customers. Now let me quantify the impact of these pressures on our margins, and then I will speak to how Wheels UP is addressing each going forward. First, the lower 1P on-fleet utility in the third quarter despite higher demand versus the second quarter impacted our adjusted contribution margin by over 200 basis points. Second, the increase in on-fleet cost per hour, driven by higher input maintenance and labor costs, created an additional roughly 150 basis points headwind. And third, higher cost for 3P supply and complementary cabin class upgrades drove the balance of the margin decline. So let me now walk you through what we're doing to improve adjusted contribution margins going forward. First, we will improve our 1P utility. We are ramping up our pilot recruiting and retention efforts. We believe that our investment in compensation, including recent equity grants, health and wellness and quality-of-life initiatives will create a compelling offering as we look to add and train over 150 pilots over the coming quarters. In addition, we are expanding our in-house maintenance capabilities as we plan to add over 100 aircraft technicians. We also expect to increase our mobile service unit capacity by 50% and institute other process changes to get our aircraft back into service sooner. The fact that we are raising pricing, the capped pricing and program changes effective December 1 will allow us to better price in this market environment and more efficiently match demand with supply. The more immediate impact will be on existing pay-as-you-go members and new members and blocks added after December 1. Third, we are working to secure more 3P capacity by significantly increasing our usage of long-term guaranteed rate programs or GRPs. We have a unique advantage from the predictability of our customer cohort spending trends and prepaid block sales to lock up supply earlier at better rates than the spot market. GRPs accounted for 40% of our third-party flying in the quarter, and we expect that will continue to increase. Fourth, we expect an increased contribution from our 2P fleet. We are launching several new initiatives, including GRPs or our managed fleet to further incentivize and grow the number of owners that charter their aircraft in our marketplace. And fifth, we are focusing on developing our technology, where we'll be looking to hire over 50 software engineers. We believe these investments will generate increased efficiencies across the organization, particularly in our flight operations, customer service and sales and marketing areas. The launch of the global aircraft search engine as Vinayak detailed should be a big step to optimize scheduling and improve profitability. While we will provide our 2022 guidance when we report fourth quarter earnings, we do expect supply constraints to persist in the near term. So as we execute on the strategies I just outlined and others, our adjusted contribution margins will likely be in the low to mid-single digits for the next several quarters. With that said, we still continue to believe we can significantly increase margins in the long term as we execute on our plan. Switching to OpEx. We continue to gain some leverage on our sales and marketing expense as a percentage of revenue. At the same time, we are planning to increase our spending on technology, including capitalized software to execute on our technology initiatives. General and administrative expenses were higher this quarter due to public company costs which should continue to come down over time as a percentage of revenue. Our challenges with our adjusted contribution margin resulted in our adjusted EBITDA decreasing $15.9 million in the quarter compared to last year. Turning to capital expenditures. CapEx was $16.3 million year-to-date, but more than half of that being capitalized software. Free cash flow defined as cash flow from operations less total capital expenditures, including capitalized software, was a negative $39 million for the quarter. At quarter end, Wheels Up had a strong balance sheet with cash and cash equivalents of $535 million and essentially no debt. With regards to 2021 guidance, given the strength in our revenue in the first 9 months of the year, we now expect 2021 revenue to be in a range of $1.115 billion to $1.14 billion. We now expect adjusted EBITDA to be in a range of negative $80 million to negative $90 million for the year. That is largely due to the lower-than-expected adjusted contribution margin we discussed and the cost of the investments that Vinayak outlined. We expect to report a GAAP net loss of between $200 million to $210 million for 2021. Reflected in this range are several noncash amounts, a $20 million charge related to the earn-out shares and a $35 million expense related to stock-based compensation, which includes accelerated success. The range also reflects a $12 million year-to-date noncash gain on the fair value of our warrants. Most of these noncash amounts relate to our transaction is aspirational and the public listing of our shares. We expect CapEx spending will be at the higher end of our $25 million to $35 million range. In order to support the stronger demand, we will likely acquire some aircraft this quarter. It's worth noting that we also serve as an aircraft broker. Our goal would be to sell at least some of the aircraft we acquired to new owners will allow us to manage or lease back those aircraft. Also, our increased technology-related investments will lead to an increase in capitalized software. From an income tax perspective, we anticipate that we will generate net operating losses for income tax purposes in the near term that may be carried forward indefinitely. In closing, I want to reiterate our Core and Business member retention and lifetime value are very important to the long-term value of the company. That is why we are incurring incremental costs to ensure our customers get the best possible experience in this environment. We are focused on execution to deliver on the promise of our technology-enabled marketplace platform and believe we can significantly increase margins in the long term as a result. With that, thank you all for joining. Let me turn the call back to the operator so we can take your questions.
