I once discovered that LaGuardia Airport's Frontier Airlines LGA Terminal had a wide variety of restaurants and stores to check out. Coffee and a quick snack were available at one of the shops, which was ideal for refueling before I left. I could keep my devices charged because there were enough seats and charging outlets in the tidy and cozy gate area. United's employees made sure that everything went as planned and that passengers received effective assistance, and the boarding process went well.
