I took the JetBlue experience last Thursday, arriving back here in USA on Wed. I will probably never take American Airlines again.
I saw exactly where my $342 fare went, and JetBlue treated all like friends. There were no meals offered, just plenty of snacks. This kept the many children that flew on my flight at bay. As did the personalized TV monitors. It's a wonder what cartoons can do. And when the little rascals got very feisty, along came a flight attendent to show him/her around the entire plane, which calmed them down and offered all passengers a relief. Pleasant flight crew, albeit mostly men.
Ticket counters in JFK are in Terminal 6. Whole check-in process including security checkpoint took about 30 minutes (10 at the ticker counter, 20 in line). Purchased my $10 visa at check-in. Pretty painless during a holiday weekend. Flight was full, and took off 15 mins late, but we arrived 10 minutes early.
Cleared STI airport in 5 mins. Had a taxi waiting outside for me. Cost me RD$350-400 into Centro, including my final stop at Hotel Platino. I had called Servi-taxi (809-581-0000) ahead, and had them send someone for my flight.
Return flight was similar. On-time, no issues. Watched as people did the many bags thing without issue from the airport, so long as they did not exceed the posted number of check-in and carry-on luggage. It was quite interesting to see 18 bags being counted for the 6 person family, and with them allowing the mother of the den to carry these huge masks that weren't even counted.
I'll just say JetBlue is dealing with things nicely, and I have a feeling many more passengers were more than pleased by the service. The Airbus A-320 fleet is very nice for this length of travel. They are working out the DirecTV bugs now, in which the 4 movie channels do not really operate over international waters. There are 20+ other channels.
I'd definitely recommend flying them.
