Lots of us over here. The move can be a bit of a culture shock depending on how you handle new stuff, alot of the wives/girlfriends had a bit of an adjustment period. Most like it once they settle in.
Bad: No timmy's, expensive beer, it's damn hot/humid for 2 months/year and everything takes about 9 times the effort and paperwork to get done as it does in Canada, the locals make Montreal drivers look good, no Canadian Tire (try finding some stuff over here if you do any DIY, course you don't have to do anything DIY cause labor is so cheap, quality leaves a bit to be desired though),remember ATC that you bitched about in canada/US?...you'll miss them soon enough after flying to Asia a few times, gulf controllers are usually decent though, you'll be appalled at how they treat cabin crew and indians (not the NA kind) and everything is beige...all the time.
Good: You'll be amazed at how well pilots are treated compared to back home, no digging your car out of a 2 foot snowbank after coming home from a 3 day pairing, no deicing, hardly any weather and the runways are all 10000'+ long (easy flying), cheap cars, car insurance, boats, gas..NO TAXES!! and 10 months of the year the weather is great for BBQ's. You can really live a lifestyle you'd never afford to back home. All in all it's what you make of it, some hate it, most love it. i know there is no way i could go back home to make $40k a year at AC.
