Yep, we have started booking our trip using one way. Big reason this year for 2018 was that our new miles hadn't been deposited into our account yet and the one way down was very cheap. We did use miles on the way back but had to book hubby and me separately as neither of us had enough to cover the whole thing. We do the credit cards to get the miles and they certainly have it all figured out. Flight attendant didn't like me questioning her about the zoning preference for AA card holders. I guess now we get Group 5 but some of our segments were 6- just like regular people. Nothing special. She had no answer and just moved on to the next victim. They promote free bags but it is only for domestic flights. 40,000 does not give you a free flight to SXM unless you want to have 2 stops and perhaps an overnight layover. Will ask more questions in April! LOL
