For example, I found seats departing Sky Harbor PHX on Wednesday, August 14, returning from St. Maarten SXM on Sunday, August 18, 2019.
Other dates are available widely available starting in April with daily flights at this price point open through October. Peak summer dates are also fairly easy to find, so escape the brutal Phoenix summer by sipping tropical drinks by the Caribbean sea.
This Basic Economy fare includes one carry-on bag plus one personal item. A checked bag costs $30 each way.
Seats will be assigned at random upon check-in for this price. Advanced seat selection can be purchased by upgrading to Main Cabin for an extra fee starting from $15 each way.
Delta and JetBlue are offering fares at a similar price, but their inventory isn't as widespread as American. If you don't like the restrictions of Basic Economy, upgrading to Main Cabin will set you back another $30 roundtrip bringing the total to $442.
