On April 10, 2008, Frontier filed for Chapter 11 bankruptcy in reaction to the intent of its credit card processor, First Data, to withhold significant proceeds from ticket sales.[better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1. According to Frontier's press release, "This change in practice would have represented a material change to our cash forecasts and business plan. Unchecked, it would have put severe restraints on Frontier's liquidity..." Its operation continued uninterrupted, though, as Chapter 11 bankruptcy protected the corporation's assets and allowed restructuring to ensure long-term viability. After months of losses, Frontier Airlines reported that they made their first profit during the month of November 2008, reporting US$2.9 million in net income for the month.

In August 2012, Travelocity faced a viral controversy when it offered a $200 coupon code to attendees at the National Federation of the Blind annual conference in Dallas. After the NFB posted the code on Twitter without mentioning the attendee restriction, Travelocity re-tweeted it without noticing the error but deleted the tweet a day later. After some travel blogs and message boards resposted the code, many ineligible travelers used the code. Travelocity responded by cancelling all trips that used the code who weren't on the list of attendees at the NFB annual conference. This resulted in a barrage of complaints from customers angry to see their trips suddenly cancelled.
