Just flew a B6/AD ticket this past weekend AUS-FLL-VCP-REC-FEN-REC-VCP-FLL-AUS. I could see my itin on JetBlue site but wasn't able to checkin online (visa check). I couldn't see my reservation at all on Azul's site. At checkin in AUS JetBlue was able to print all 4 boarding passes.
FLL-VCP was on an A330, I had regular seats but apparently they were offering buy up to the extra space seats for $40. Regular seat was OK and I'm tall at 6'. In-seat video was the same screen as AeroMexico 787/United 767-400 (touchscreen, USB charger).
In-flight service was good, snack basket like Jetblue. They have cool retro-looking postcards for the menu

.
Arrival at VCP at the new international terminal (T1) but you must bus over to the old terminal (T0) for domestic connections. There is a Priority Pass lounge in T1 but no lounge at T0.
No ATMs that I noticed in T1, strangely but there is a Bank/Cambio that was closed at arrival time (6AM). There were ATMs in T0.
