Good Luck with your interview, from my understanding the base in PHX at the moment is overstaffed so I am almost 90% certain you would be either based in PHL or CLT, with a very small chance of DCA (as it is the smallest east base). The reserve system at US at the moment is very old school, West reserves are running at about flights attendants that have been flying for 7 years or less and out East I have met F/A's on reserve with up to 20 year seniority- so not the best system. The new contract apparently will be changing how the resevre system works. I am not a f/a so I don't have all the fine details but if the contract gets voted in I'm sure some things might change and both east and west cabin crews will start flying toether (not overnight I'm sure).
