Transfer at SJU

Its worse at peak times of the day like 8am and 5pm, but you should be ok. I would risk it over the 12 wait.

If you're traveling from SJU to STX by sea plane, fifity minutes is impossible. If you're traveling from SJU to STX on American, fifty minutes is tight but if you don't make it, they'll put you on the next American Eagle flight. Other airlines have less flexibility.

Its though AA, pretty much the only airline we could find to go from YYC to STX

If your arriving and departing flights are both on American and you book it on their website as a single itinerary and not as separate flights, then you should be in luck. They will either get you to SJU in time to run to the next gate for your continuing flight or they will put you up in a hotel overnight and send you across in the morning if your arriving flight is delayed. If you book them as separate flights, then they won't guarantee that the transfer time is sufficient and you would be on your own for the night if you arrived late, although they probably would cooperate with moving you to the flight the next morning without charge. If you do make it onto the flight on time on a tight connection, don't be surprised if your luggage is delayed until the next morning's flight. This happens quite often. Be sure to have enough stuff in your carry-on to get you through the night wherever you might wind up.

I have yet to do this but. I am investigating the possibilities. There are direct flight into STX from Miami, thus missing SJU. I am finding that there are also direct flights to STX from New York. I don't know where you are coming from... but I get the idea that missing SJU is a good idea. I am currently trying to book directly from Miami and avoiding SJU. If you have any luck...let me know...

I don't believe there are any direct flights from NY to STX. Can you tell me which airline you think flies direct from NY to STX.

I just checked on expedia and it lists direct flights between NY and STX on American Airlines but on the AA site there are no direct flights????

Flights change daily - Expedia may not have been updated. There was someone on the vacation forum who had the same thing happen to them, and it was on their honeymoon.....they had no idea there had been a change of itinerary.

Always better to book directly with the airline if you can, but that doesn't assure you that things will be tomorrow what they are today.

Wait - are you talking direct flights or nonstops? I doubt seriously there's a nonstop from anywhere, but I could be wrong.

direct and non-stop are two different things in airline parlance. Direct means you remain on the same plane for the entire trip even if you land for a layover somewhere. Nowadays you have to get off the plane and reboard, so it's not much different than a transfer other than not having to run a mile to another gate.
