Paper or Plastic?

Q: I flew on Frontier Airlines recently and was shocked to discover that they didn't accept cash payments for inflight TV and alcoholic beverages. Are there other airlines that don't accept cash? I was forced to declare bankruptcy last year and therefore don't carry credit cards.

A: A few other smaller airlines have also stopped accepting cash for drinks, entertainment, food, and other in-flight purchases. These include Aloha, Airtran, ATA, Hawaiian, and Spirit. I expect that at least some airlines will follow suit. Frontier claims that this move will speed service. Think of it this way: if you're using an airline-affiliated credit card you'll get a free trip that much faster.
