According to FlightGlobal, David Siegel joined Sun Country Airlines as Executive Chairman earlier this month. This can be confirmed via Mr. Siegel's Linkedin profile. He previously served as CEO of low cost carrier Frontier Airlines from 2012 – 2015 and US Airways from 2002 – 2004.
With this latest addition to their executive team, it would appear that Sun Country is taking their transition to an ultra low cost carrier (ULCC) seriously. Sun Country previously hired Jude Bricker as President and CEO last summer. Mr. Bricker was previously employed as COO of low-cost-carrier Allegiant Airlines.
When Sun Country announced in December that they would be purchased by Apollo Capital Management (Apollo), I wasn't sure how long the firm would hold onto the company. It would appear that Apollo is in it for the long-haul and is quickly building an experienced team of former executives from competing budget carriers to help grow Sun Country and guide the company as it fully transitions to an ULCC.
It has not been a quiet month for Sun Country. It is unknown if Mr. Siegel was at the helm assisting with decision making during the recent Mexico fiasco. It's safe to say that Mr. Siegel & Mr. Bricker will have their work cut out for them as they work to rebuild Sun Country's tarnished reputation.
