I found seats for a trip over Valentine's Day departing Boston BOS on Thursday, February 7, returning from Guatemala GUA on Friday, February 15.
Other dates are available for travel throughout the year leaving as soon as today or tomorrow. There is no advanced purchase required. Departures in late June and July have higher fares, but this price can be found on flexible travel dates in most months.
See our fare details for booking info.
