My experience with interviews is typically the harder the interview, the better the job. This pretty much runs true for pretty much any position. As you know, the US Airways interview was a joke, when you applied their pay rates were dismal and very few people wanted to work there. I think it would've taken me EIGHT years to just get back to the same hourly pay as an RJ CA while riding right seat in an Airbus, and that didn't include any of the rigs I had as an RJ CA whose contract was infinitely better. In fact as you know RJ CAs who hustled made similar money to topped out US Airways A320 CAs.
Contrast that to the difficulty in even getting an interview at the better legacies.
