Southwest Airlines Receives First 737-800

In an effort to transport even more passengers on board its all-737 fleet, Southwest Airlines received its first 737-800 this March. So far, Southwest only operated smaller versions of the 737, such as the 300, 500 and 700 versions. According to the Orlando Business Journal, Southwest's 737-800 will feature 175 seats, 38 more than the airline's other 737s. Southwest will add an additional flight attendant to the 800s, of which the Texas-based airline ordered a total of 73, to accommodate for the additional passengers. The 800s will be ETOPS configured upon delivery.

Southwest will likely use the 800s on routes originating or arriving in the Northeast where additional slots are either unavailable or very expensive, such as at New York's LaGuardia airport. The airline could also use the ETOPS 800s on longer and over-water flights to places like Hawaii, Canada or the Caribbean.

In December 2011, Southwest also placed an order for 150 737 MAX 8 (and/or 7) planes, with the option of receiving an additional 150. They are slated to enter service in 2017.
