We are spending a week in St. Martin in July and are then going to spend a week in St. Lucia. We are flying on LIAT airlines leaving SXM at 3:30 and arriving in Antigua at 4:10. We leave Antigua on a different flight at 5:20 to go to St. Lucia. Since we have never done this, what can we expect at Antigua in terms of the transfer, i.e., luggage, customs and immigration? Is that enough time in between?
