 When Darrell Plunkett had to change his Spirit flight from Fort Lauderdale to Atlanta, he was worried the ultra-low-cost airline would hit him with a fee. They were flexible, actually got a credit back, so, I mean, I'll give them their kudos on that. But Spirit, known for its a la carte, or pay-for-everything approach to travel, just dropped its change and cancel fees while also upping the wait for checked bags to the industry standard 50 pounds, as it looks to win back flyers.
