Travelers using a flexible search feature on the United Airlines site came up with a slew of low round-trip fares from different U.S. cities.

The low fares were found for dates between Wednesday, October 26 and Tuesday, November 1, 2016. A 10-day advance purchase is required for the tickets, said Airfarewatchdog.com.

Some of the low fares found to and from San José’s Juan Santamaría International Airport (SJO) from the following cities were as follows: Houston, $263 RT, Newark, $342 RT, Boston, $309 RT, and Miami, $248 RT.

There is a reasonable amount of seat availability at these prices. Flexible travel dates may be required to find the rates mentioned above and seats may not be available on all flights or all dates of travel. Holiday periods may be excluded. Wednesday travel seems to be the best day for the low fares.

All mandatory taxes/fees are included in the price. The tax-inclusive fare may be a few dollars higher or lower depending on the airport you connect through, if any. Baggage fees, if applicable, and other optional fees are not included, said  Airfarewatchdog.com.
