BofA/Merrill downgraded Allegiant Travel to Neutral and lowered its price target to $175 from $205 following the Q1 report and a significant increase in its 2017 cost outlook to +9%-12% from +5%-9% driven by Airbus fleet costs, higher credit card fees, and early retirement of some MD80s.

Travel + Leisure Co. (TNL) and Allegiant (ALGT) "announced a multi-year marketing agreement, allowing both companies to grow their customer engagement through cross-company promotion. The two travel companies will share promotional offerings to each other's customers, providing offers to a broad spectrum of travelers. Allegiant, with more than 15 million Allways Rewards members, and Travel + Leisure Co., with more than 800,000 vacation ownership members and 3.5 million vacation exchange members, will each benefit from a highly engaged base of travelers."
