Airline Trouble

ABC News: Fourth Carrier Files for Bankruptcy
You know how I was talking about a trip to Portland in June? I'm getting a little worried. See above.

Frontier is the main Denver airline and is who we almost certainly would be flying with if we were to go. If I buy tickets now and then in June, the airline is not flying flights or no longer in business, I'm pretty much screwed, yeah? Should I be worried about this?

We need a vacation, but we've been considering a drive around Colorado instead to save money, but still leaning towards Portland. With this news, I am starting to reconsider yet again. What do you think?
