We flew EWR - SXM r/t in April. They did allow us to check in the 24 hours ahead but we were not able to print boarding passes. Had to show the appropriate forms at the airport but we were checking bags so had to do the lines anyway. We travelled down on a Friday and the lines were GEnormouse…. 🙂🙂

IMHO it was much more organized in SXM than EWR but maybe it was just a bad day.

Coming home we again did the check in on line and we were able to print the boarding passes too. We did the attestation on line and had printed copies of everything jic. The SXM people thanked us for doing the printed copies as opposed to fumbling around with cell phones as it wastes a lot of time. That last is a guess on my part but they did appreciate everything in print.
