If my flight is canceled

We are flying to SXM on Sunday. If our flight is canceled, and we rebook, for the next day, do we need so resubmit our paperwork? Flight numbers and dates would all be different.

It would not hurt do so, as EHAS has been responding fairly quickly, but SXM has also been accepting existing paperwork for flights that were cancelled on the prior day. Also, if your flight is cancelled, you can just send them an email asking for confirmation of acceptance of your existing pre-approval.

I hope everything works out for you, so you don't have to worry about it!!

They have been accepting EHAS stuff that is a day old, but it can't hurt to re-submit. Best wishes!
