Southwest has round-trip flights from Dallas (DAL) to San Jose, Costa Rica (SJO) for $345 with a connection. Flights August, September, October, November, January, February, and March. Very few weekends available. Origin/Destination reversible. No Thanksgiving dates.
Yes, we know that Viva Aerobus (a budget carrier similar to Spirit) often has fares in the $270 range. We advise you avoid those, as Viva fares are more expensive once you add in bag/seat fees.
