Thanks, Emily, and good morning, everyone. In 2021, Alaska has established a track record of leading the industry in the recovery from the pandemic. This has been enabled by the strength of our business model, our measured approach to capacity and our financial discipline. Our 2.4% pretax margin in the fourth quarter continues that trend, especially considering the disproportionate impact that severe weather had on our hubs, and the Omicron-related impacts we began to face at the end of the year. While I'll discuss the impact of weather on our fourth quarter and the impact of Omicron on our first quarter, let me start by saying both of these are temporary challenges that do not deter my confidence in our underlying business model and its ability to outperform the industry. Starting with recent events. The combination of severe snow, multiple consecutive days of sub-freezing temperatures in our Pacific Northwest hub and stacking disruptions caused by the Omicron variant, resulted in one of the challenging holiday travel periods we have ever experienced. Our completion factor was extremely challenged at the end of the year, which resulted in flying approximately one point less than our expected capacity in the quarter and 2.5 points less than we planned to operate in December alone. I want to apologize for letting our guests down during one of the most important travel periods of the year, and I also want to acknowledge the strain our teams were under as everyone worked to stabilize the operation. In terms of the financial impact of these events, they were material. Our fourth quarter result was worse by approximately $70 million, and our pretax margin was reduced by 3.5 points. Even with this outsized impact, Alaska was profitable in Q4 and strongly led the industry in pretax performance over the second half of 2021. In response to the ongoing impacts of Omicron in early January, we proactively reduced our remaining Q1 scheduled client by about 10%. I am pleased to report that Omicron absences are down significantly and our operation is once again stable. Omicron has not only impacted our ability to operate fully and has dampened closer to the main substantially as well. Andrew will provide more detail on the demand environment but the silver lining is that demand for travel from presence date and beyond remain strong and booking trends have rebounded week-over-week since their low point in early January. We expect the bulk of the Omicron impact to be felt in the first quarter, specifically in January and February as revenue has reduced and as unit costs are pressured given lower ASM production and higher staffing-related costs. However, as I opened with, this will be short term in nature and has not changed our expectations about the overall recovery. Clearly, this was a tough way to end a year that otherwise had progress worth celebrating. And in that vein, I want to acknowledge that 2021 was a year of significant recovery and highlight some of the important successes from the full year we've just closed out. First, our revenues recovered to $6.2 billion or 70% of 2019 levels, and we achieved this while flying less capacity than many of our peers who had similar revenue recovery results. Second, while the full year adjusted pretax loss was $342 million, we recorded $282 million of adjusted pretax profit during the second half of the year. Our second half adjusted pretax margin was over 7%, clearly outperforming the industry even though West Coast travel has recovered slower than much of the country. Third, with decent demand recovery and disciplined cost management, we returned to positive operating cash flows. Excluding any CARES funding, we generated more than $100 million in operating cash flow for the year, which reflects $100 million pension contribution we funded in the third quarter. Fourth, as profits and cash flow returned to positive territory, we have essentially repaired our balance sheet. We closed the year with a 49% debt-to-cap ratio, 12 points lower than prior year and within our target range. And lastly, given we were able to meet or exceed several of our recovery goals, our employees earn the industry's highest bonus pay through our incentive-based pay program. For the average employee, this payout amounts to about 6.2% on top of their annual pay. All told, I'm really pleased to report that our bonus programs will pay out $151 million to our employees for the year. In addition to these financial milestones, we also cemented several critical strategic decisions during 2021 that will help drive our success well into the future. We made the decision to return to a single fleet of Boeing aircraft, which will drive revenue and cost benefits. The remaining 27 Airbus A320s that are flying today will be retired by the end of 2023, enabled by our Boeing MAX order of 93 firm and 52 options. We joined One World and launched our West Coast international alliance with American Airlines which will unlock additional revenues and loyalty across our West Coast hubs, especially in Seattle. We announced sustainability goals, committed to net-zero carbon emissions by 2040 and further embracing a sustainability mindset by linking a portion of our annual performance-based pay plan for all employees to the carbon intensity of our operations. And we renewed our commitment to diversity, equity and inclusion by establishing a five-year goal to increase leadership representation and match that of our front line. We also integrated this goal into our executive compensation targets. Let me close with a brief look ahead at 2022. Like our industry peers, Q1 will clearly be impacted by Omicron both for revenues and unit costs. We do believe that virus will move to endemic status and that demand will ultimately stabilize. And when it does, our business model is set to outperform. Notwithstanding a challenging first quarter, we expect to be profitable for the month of March and for the remainder of the year. We remain committed to returning to pre-COVID capacity by the summer and plan to grow from there. I expect full year capacity to be up versus 2019 between 2% and 6%, dependent on demand. This guidance reflects first half capacity that is flat to slightly up and second half capacity that could be up as much as 10% versus 2019. As we did throughout 2021, we will continue scaling our business back in a measured way, leveraging our strong balance sheet and running our operation to produce consistent industry-leading financial performance in 2022. I hope you'll join us at our upcoming Investor Day. We plan to share our long-term expectations, including comprehensive 2022 guidance. This event is set for March 24 in New York. Before I hand it off to Andrew, I want to thank the people of Alaska and Horizon for all that they do. It is no secret that this is a tough business, but the pandemic has surprised and challenged even the most seasoned in our industry. The strength of our company comes from our people and culture of care, our focus on safety and operational excellence, our reputation for customer service and our financial discipline. I am confident these strengths will serve us well again in 2022. And with that, I'll turn it over to Andy.
