• Gregory Clark Anderson (CEO & Director): "For the shareholder vote and the regulatory approval or the HSR filing, we expect, Mike, to file both of those within the coming weeks."
• Gregory Clark Anderson (CEO & Director): "And with the Sun Country acquisition, just the work that B.J. and the team have done to strengthen the balance sheet over the years and the way we structured the deal, this isn't going to -the acquisition isn't going to stretch us by any means."
• Gregory Clark Anderson (CEO & Director): "In fact, post-close and integration, its going to strengthen the balance sheet. We have a favorable well-timed match order and you combine that with the free cash flow that Sun Country is currently producing, that's going to help us not only maintain a low leverage, but continue to deliver post combination."

• Robert J. Neal (President, CFO & Executive VP): "But if the timing doesn't work out, there's more than $1 billion in unencumbered aircraft and engines. Candidly, cash balances for the first quarter are ahead of schedule. We could start by just using cash balances if we need to."
