Delayed over 3 hours, extremely rough landing on all four flights. Would not recommend

Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

Overview of Southwest

Marketing itself as a low-cost airline, Southwest Airlines operates predominantly domestic flights within the United States. The airline flies to 41 of the country’s 50 states. Flying to a further 10 countries, there is a focus on Caribbean destinations such as Jamaica, Cayman Islands, Cuba, Aruba and The Bahamas.

All flights are scheduled using a point-to-point system, which is decentralized and relies loosely on the airline’s hubs. In comparison to the hub and spoke system commonly used by major airlines, Southwest Airlines reduces the likelihood of baggage loss and fuel consumption per passenger. With less connections and travel time, you can get to your destination faster.

Videos of Southwest Airlines’ safety announcements have gone viral, with the cabin crew regularly mixing in tasteful humor. As they engage the passengers and build a warm atmosphere, make sure you take your headphones out and listen in. Specific seats are not allocated and customers are free to choose their own seat. Complimentary app messaging is provided so that passengers can use WhatsApp and iMessage during the flight.

The fleet is made up exclusively of Boeing aircraft and has used the 737 family series since 1971. A bold livery featuring a dark blue body and orange and red stripes has become the customary design.
