When I first started as a F/A with UAL making (sad to say but what regional F/O's start at now) nothing, I kept my home address as FL to save the taxes even while having an apt in Chicago......Took the train to work, so I didn't need the car and kept it in Fla too, for those beach trips on days off......I don't see why you can't keep it FLA, UAL doesn't care what you put down, just keep in mind all your union/company/insurance and any other important mail will go to your "home" address.
