In our case (notified end of last month), we were given (a) a mid-Dec. Bios date when I was supposed to be halfway around the world, (b) Lisbon when our house, my spouse (on holiday) and our GV advisors are all in Madeira.
For a few angry hours I thought about asking AIMA to reschedule to a place and time that made any sense. But I knew contacting AIMA was futile, and instead spent a couple thousand more changing 3 existing flights + 1 new one (at Christmas season prices) to be in Lisbon.
… as I spent all night on the phone with airlines, hotels, etc. changing dates to suit AIMA, I actually felt a bizarre sense of empowerment. I call a service, someone answers within a minute, and for a serious wad of money does what I want, and commits to deliver said service on the day I asked. And barring weather, war or pestilence there’s an excellent chance they will deliver. Crazy, huh?
