It is one of the simplest and most convenient airport experiences I've ever had, as I can test from my recent flight on Southwest Airlines LGA Terminal from Terminal B at LaGuardia! The process was easy from the moment I came in thanks to the helpful staff and check-in kiosks. With options like TSA PreCheck and CLEAR, which helped keep lines short, security was a snap. In addition to security, there is free Wi-Fi, lots of comfortable seats with charging stations, and a large selection of food options, ranging from full-service restaurants to bagels in the New York style. Southwest made traveling less stressful with their accommodating rules, like free bags and simple ticket modifications. To be honest, Southwest at LGA provided for a seamless, pleasurable beginning to my journey with efficient boarding and a tidy terminal.
