After we had booked our flights on St Barth Commuter, Delta Airlines changed our return flight from 4:23 pm to 3:20 p.m. on Sat. Feb 25 and there are no seats available on the 12 noon flight on St Barth Commuter. We are booked on the 1 p.m. flight - will that give us enough time to check in/clear customs and immigration in St Maarten or do we need to cancel that leg and book an earlier flight on Winair? Thank you in advance for your insight and experiences.
