John, thank you and thank you everyone for joining today's call. 2023 is off to a great start as reported in our first quarter results. The team delivered meaningful improvements in operational areas across the Board, most notably a terrific 99.9% controllable completion factor with an industry-leading 99.1% completion factor. This operational excellence was evident in our financial performance as our total irregular operational cost came in just below $9 million, that is down $57 million compared to the same period in 2022. I couldn't be prouder of this team's performance, and I'm happy to report an update on our C-suite and that is the Keny Wilper, who has served as our Interim COO since January, has been appointed as our permanent Chief Operating Officer. Congrats, Keny. You have our full support and confidence. This is one of the most exciting times I have experienced in my history with Allegiant. Our leadership team is strongly aligned and our team members are dedicated to executing and strides and rethinking process to become more productive and to strengthen this organization. For example, our planning, finance and operational teams continue to work together shoulder-to-shoulder on a multi-disciplined approach to drive operational excellence while expertly matching capacity with demand. Recently and to preserve operational reliability, the team trimmed full-year capacity 2.5 points now guiding zero to 3% ASM growth. This is a result of MRO delays for aircraft and heavy maintenance, pilot constraints, but along with airport construction disruption and ATC delays in some key markets, particularly during peak travel days. Even with this reduction in guided capacity, we expect improvement in full-year airline earnings to $11 per share, an increase in our full-year guide of EPS of $4 per share. We believe our measured approach coupled with our differentiated model, sets us up well to deliver industry leading results regardless of the broader macro environment. As mentioned last quarter, we have incorporated within our EPS guide the expected cost increase for our open labor agreements. The actual increases in compensation will vary depending upon economic terms for each and the timing of these agreements. This increased compensation was initially incorporated into our full-year EPS guide beginning in July. However, we have now moved this date up to May 1st as we fully expect to be paying higher rates in the near future once agreements are finalized and approved. In fact, I'm happy to announce we reached a tentative agreement on a contract extension with our dispatchers represented by the IBT. This agreement will modify the final pay rate increases in the CBA and provide a two-year extension on their current CBA. I think it is important to note that this contract did not even become amendable until May 31st of next year, but the parties work together to bring this meaningful improvements to our dispatchers today. And as John mentioned, we are still in active negotiations with our flight attendants represented by TWU and our pilots represented by IBT. Resolving our open labor agreements is our highest priority. Negotiations with our flight attendants opened eight months ago and we are quickly closing in on the outstanding open items. Both sides are very pleased with the progress that has been made, and we look forward to announcing a tentative agreement very soon. On the pilot front, we had our first mediation sessions with the IBT last week with another session taking place next week. After working to highlight and identify the gaps in each side's proposals, all parties left the first sessions encouraged by the possibility of finding a path to an expedited deal. As a result, the mediators have already provided numerous additional dates to continue to work together towards resolution. Touching briefly on our current pilot staffing, our net head count for the year remains roughly flat and consistent with the trends message last quarter. However, within our schoolhouse, the number of new hire pilots are outpacing our initial expectations. With the strong recruiting team and pathway programs in the works, we remain confident in our ability to attract, train, and grow pilots. Allegiant is uniquely set up to be the destination airline for our team members. Our out and back model is built around our flight crews having the opportunity to be home every night and that is something they highly value. We look forward to reaching agreement with our flight attends and pilots, and provide compensation and work rules that they can be proud of and most importantly, they deserve. Turning briefly to our systems transformation, we continue to make significant progress on our four core system integrations, Navitaire, SAP Tracks and NAVBLUE. First up will be Navitaire, which we expect to go live this quarter. It enhanced functionality in our commercial platform is expected to unlock additional features to drive higher ancillaries and bundles. In addition, Navitaire provides the necessary functionality for us to expand internally in New Mexico through our joint venture with Viva Airbus. While we are still awaiting DOT antitrust immunity, we are confident in this outcome. We are fired up about this partnership and its unique ability to provide incredible value to our guests and more growth opportunities for our team members. And in closing, these results cannot be accomplished without the efforts of Team Allegiant over the past 90-days, I have had the amazing opportunity to immerse myself more broadly throughout the organization and in particular with our frontline team members. Each visit has been exceptional for me. I have the privilege of meeting the best team members in the industry, a learning experience that provides me with the insights to continue to assist and help those in the field that everyday provide our guests with a safe, reliable, and convenient product. I want to thank each and every one of them. And with that, I will turn the call over to Scott DeAngelo, our Chief Marketing Officer.
