For winter travel, fly from Dallas to San Jose, Costa Rica for $198 roundtrip on United.
As an example, I found seats departing Dallas DFW on Wednesday, February 6, returning from San Jose SJO on Friday, February 15. Perfect for a week-long Valentine's getaway.
Other dates are available on a few dates in late January and early February.
This is a Basic Economy fare, which only includes a small personal item and other restrictions apply. A checked bag will cost $30 each way. If you only want to bring a carry-on bag in addition to your personal item, make sure to pay for the standard Economy fare, which is $248 roundtrip, and also includes standard seat selection and fewer restrictions.
For booking info, see our fare details.
