Southwest returns to Costa Rica

Daily service to Costa Rica will begin on June 6th, 2021. From William P. Hobby Airport (HOU) in Houston, Texas, Southwest will fly daily to Daniel Oduber Quirós International Airport (LIR) in Liberia, Guanacaste, Costa Rica. A second daily flight to Costa Rica will run to Juan Santamaría International Airport (SJO), serving San Jose, the capital of Costa Rica.

Seasonal service from Baltimore/Washington International Thurgood Marshall Airport (BWI) will run to LIR this summer. The nonstop flights will run on Saturdays. Baltimore to Costa Rica service starts on June 12th.

Costa Rica is open to US citizens. The country requires inbound travelers to provide proof of a medical insurance policy to cover quarantine or medical treatment. Double-check entry requirements before leaving for your trip, as restrictions can change based on the public health situation.

International destinations have been slower to come back to Southwest’s network. The airline plans to fly all of its international destinations by the end of 2021, assuming that the demand environment is far improved and travel restrictions come down. According to Southwest, the markets it is currently serving abroad are seeing strong demand.

Targeted growth

Southwest has been focused on rebuilding its leisure schedule. Additional flights will come to Cancun and Los Cabos in Mexico and Montego Bay in Jamaica. Southwest will fly 22 departures to/from Cancun on Saturdays from 13 cities in the US.

Increased daily flights will come to San Juan, Puerto Rico (SJU). From here, daily flights will run to MCO, MDW, and TPA. Puerto Rico is a domestic destination in the Caribbean.

In March, Southwest significantly expanded its domestic schedule, adding about 1,000 flights almost overnight. In addition, the airline has added plenty of new destinations and has more on the horizon. That has helped contribute to an increase in the airline’s capacity.

All of those new cities have been doing very well for the airline, and so far, those new destinations look like permanent additions for Southwest. As a result of the new destinations, Southwest’s route network will look different, and the airline is not afraid to add new routes where it can.

For example, this June, Southwest will fly 96% of its June 2019 available seat miles (ASMs), which is essentially 96% of the carrier’s capacity from 2019. that capacity will be deployed in different markets, including alongside new routes.

For example, Miami is getting plenty of love from Southwest with four new routes. Southwest has been in Miami since November. Meanwhile, more mature Southwest markets like Denver and Kansas City are getting three new routes and other returning routes, indicating residual strength in existing markets.

One of the biggest takeaways from this latest expansion is that Southwest is starting to repair its point-to-point network. Through the crisis, the airline pivoted slightly away to take on more connecting passengers in a bid to keep its planes full. Transit passengers are still a large chunk for the airline, but the new summer expansions should help fuel a return to point-to-point.
