I've heard that this one specifically is a lot of fun and they actually pay you. I always wanted to do a summer internship, but thought it would just add 3-4 months to getting hired at my first airline. In hindsight, if I had done an internship I'd still be instructing instead of sitting right seat in a fancy new jet getting payed peanuts. The regionals won't be hiring for a while, so take advantage of this lull in the industry and go do something fun and off the beaten path.
