I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

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.

Unlike most other American airlines, you are allowed 2 checked bags for free with every ticket purchased. Another customer benefit is that there is no change of flight fees, meaning you only need to pay the difference of the cost of the tickets. If you switch to a cheaper flight, a credit is provided for future use.

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.
