I'm not on the 'bus, but destinations move from one type to the other. Most all layovers are around 24 hours. A few longer, a few shorter. I can tell you, the hotels you will stay in are not on the par with what most US carriers "hole" you up in. Much better. But, many great cities you layover in, your hotel will be by the airport, like Rome, Paris, London. IAH will probably be a 48 hour layover, not sure. The only problem I see you might have is the embarrassment of identifying yourself as an Airbus pilot...........only kidding girls.
And you just might be honored to fly with mensaboy, he loves all things American.
The month you are on reserve, you can work your but off or not. Just like anywhere else. Any other relevant questions, I would be happy to answer, just send a PM.
