Thank you, Robin. I want to start by expressing my deep gratitude to Robin for his leadership and friendship over the years. He deserves tremendous credit for building JetBlue into the company we are today. He transformed us from a small domestic airline to one with a global footprint. He created new ways to innovate and challenge the competition from free onboard Wi-Fi to Mint our award winning premium offering which has disrupted Transcon and now TransAtlantic business class. On behalf of the entire JetBlue team. We wish him all the best in his next chapter. I'm honored to be taking on the role of CEO on behalf of this incredible company at a very pivotal moment for our business. JetBlue has a strong foundation underpinned by a truly exceptional brand and the industry's best crew members. We're building on this foundation as we take aggressive action to get back to profitability and intensify our focus on delivering value for our shareholders. Before I begin my remarks, I'm thrilled that my first leadership appointment was announced yesterday, promoting Warren Christie to Chief Operating Officer, effective February 12. Warren has a robust aviation career spanning 30-plus years from his leadership and service in the military to his Jet Blue career beginning 21 years ago and spanning various roles. Warren’s dedication and passion for safety, operational performance and service excellence has been instrumental in our evolution. And he's well positioned to help us execute a plan that will mark the start of JetBlue’s next major chapter. As Robin mentioned, we've been hard at work evolving our standalone organic plan to restore profitability and reset JetBlue for future growth. And we've already begun to implement some of the initial components. The key strategic challenge we've always faced is how to thrive as a small player in an industry dominated by four large airlines. We now face this challenge in a post-COVID environment, where industry dynamics are coalescing around some clear trends. For example, customer travel preferences, including a premium onboard experience and improved customer service. These are increasingly shifting towards JetBlue’s strengths. We will deepen and strengthen our competitive position as a unique brand with a superior customer experience, finding new ways to be the best at what we do, and further distinguish ourselves from the competition. This begins with refocusing on our most proven geographies. Our core network sits in some of the largest markets in the world where there are clear barriers to entry. And we intend to capitalize on our deep relevance in these markets by urgently re optimizing our network to make sure that we're taking care of our core customer, making sure we go where they want to go when they want to go. We're also recharging our innovation DNA, to bring an even better quality experience to the full spectrum of JetBlue customers, from leisure to visiting friends and relatives, to corporate and premium travelers. This means segmenting our onboard product offering more precisely so that each customer can get the best travel experience at the best price. We will use this new chapter to improve how we merchandise to our core suite of customers. And to the extent there are opportunities across certain customer segments, we will launch new revenue initiatives and close the gaps on our product offerings. All of this is underpinned by a more reliable operation, a complementary loyalty program and a strong culture with a competitive cost structure. In many ways, this means refocusing on our core strengths. Let me be clear, it is not however, business as usual. I commit to you that with a renewed focus, we are bringing more data-driven rigor, intensity and creativity than ever before, with a relentless focus on building value for our shareholders. Over the coming weeks and months, including at an Investor Day, we will host in May, we will be sharing more with you on our longer term plan. But today, I want to share our 2024 priorities, a preview, if you will, of how we intend to return to sustain profitability, and how we are taking urgent action, including launching several initiatives in the first quarter. Starting with our new initiatives, these are aimed at evolving our offerings to better serve our core laser customer, while further diversifying our revenue streams. In this process, we've identified over 15 different revenue initiatives. And in 2024, we expect these to add over $300 million to our top-line, of which nearly two thirds is ancillary revenue. Included in these initiatives is our recent launch of preferred seating, which provides customers with the option to select more desirable seats closer to the front of the aircraft. This also gives us another way to reward our most loyal mosaic customers who will get this additional benefit for free. And it enabled us to better match our product offerings to customer demand. Another example I will highlight is our expanded distribution and OTA partnership. This expansion further aligns our distribution capabilities with the legacy carriers, allowing us to reach more customers and giving those who are aligned OTAs greater access to our product. We're also making changes to how we manage our network rebalancing to deploy the right mix of routes and applying even greater discipline to our assessment of underperforming markets. As part of this refinement, we are aggressively reallocating capacity to proven leisure and VFR markets, including doubling down in those markets, where we can leverage JetBlue Travel Products superior offerings to better serve customers and help us generate higher margins. Our loyalty program also remains a priority as we look for additional ways to provide more value to our customers and we expect our TrueBlue program to continue to drive margin accretive growth, as we execute our multiyear plan to close the gap to peers and better monetize the program. We are expanding our suite of products with the continued goal of appealing to more of our core customers and plan to launch several new loyalty products in the coming years. Next, continued costs and capital discipline are a top priority. To that end, we have reached an agreement to defer $2.5 billion of plant aircraft CapEx and smooth our delivery stream. Ursula will provide more detail in her remarks. Finally, as we operate in one of the most complex and challenging air spaces, operational reliability is foundational to all of our priorities, helping us deliver a better customer experience while also improving revenues with fewer refunds and disruption vouchers and better costs as we mitigate overtime and premium pay. This will be a continued area focus in 2024 as we make more targeted investments in our operation, prioritizing areas such as predictive aircraft maintenance and scheduling enhancements, where we are already seeing meaningful returns for reliability. As I mentioned, we will share more at our investor date later this year. Shifting now to our fourth quarter results. We delivered a strong end for the year as both revenues and costs exceeded our expectations. Fourth quarter revenues declined 3.7% year-over-year ahead of our December guidance update, driven by healthy close in demand with both strong peak holiday period demand and better than expected performance during off peaks. Our premium offerings, and even more space in particular, continued to perform extremely well with double digit year-over-year revenue growth in the fourth quarter. We also benefited from continued strength in our redesigned TrueBlue loyalty program within the fourth quarter and for the full year. In 2019 we have had the fastest growing loyalty program any major U.S. airlines, growing revenues by 75%. This reflects strong performance in our Barclays Co-brand portfolio, which achieved a record high for JetBlue Co-brand spent and generated over $1 billion in cash remuneration in 2023, more than double our 2019 performance. We continue to make enhancements that unlock value for our customers by expanding ways to earn and redeem points, which helped fuel record growth in redemptions in 2023, growing by over 25% year-over-year. We expect continued growth going forward, as we recently launched our first seamless partner redemption relationships with Qatar and Hawaiian in the fourth quarter of 2023. And I'm pleased to announce that we have additional new partners coming on board this year. Capacity in the fourth quarter grew 3.3% year-over-year, above the midpoint of our initial expectations, as our strong operational performance in November continued through the end of the year. We operated with high load factors during the peaks and extremely busy time of year. And despite weather issues, we were able to recover quickly and minimize cancellations when dealing with storms early in the quarter enduring holiday peak. Our completion factor for the quarter was 99.8%, which is our best fourth quarter completion factor since 2004 and was one of the best in the industry. And we continue to see momentum on this front headed into the first quarter. More broadly, we saw year-over-year improvements across nearly all of our operational metrics in 2023, reflecting the benefits of the structural investments we are making to improve reliability and boost resiliency. Strong operational performance, coupled with our continued cost discipline resulted in fourth quarter CASM ex-fuel ahead of our expected range, as Ursula will discuss. Looking ahead for the first quarter, we are seeing positive momentum in our revenue. Demand during peak periods remain strong and we have better match our capacity to demand during off peaks. International demand remains very healthy and the domestic revenue environment is improving as industry capacity has been moderating. For the first quarter, we are forecasting revenues to be down 5% to 9% year-over-year at the midpoint in factoring in our capacity outlook of down 3% to 6% year-over-year. This represents a 5-point improvement in year-over-year unit revenue growth versus last quarter. Looking further ahead to the full year, we are well positioned to achieve roughly flat year-over-year total revenue growth, which we believe represents a positive outcome any year when capacity is decreasing. While the first half of 2024 cycles against the high pent up demand we saw in the first half of 2023, we expect year-over-year revenue growth to be much stronger in the back half of ’24, as comparisons ease and the benefits from our enhanced revenue initiatives grow. I'd like to close by thanking our crew members for their commitment to delivering a safe and reliable experience to our customers. These investments we're making position us to deliver the JetBlue experience better than ever before, as we refocus our efforts on serving our core customer. We are increasing our efforts to drive reliability and consistency in our operations, product and service. By digging deeper to do more of what we do best, we will be able to compete more effectively return to profitability and ultimately expand margins and returns for our shareholders. With that, over to you Ursula.
