Aer Lingus Airlines BOS Terminal +1-888-839-0502 The Aer Lingus Airlines BOS Terminal was easy for me to navigate. The majority of foreign flights run out of Terminal E, which seems roomy and contemporary. Employees at Aer Lingus smiled as they greeted us and sped up the check-in process. I had fun perusing a couple duty-free stores after getting through security. It was convenient that the terminal had excellent lounging areas with charging stations. Staff made sure everything went smoothly, and the flight boarded on schedule. Thanks to Aer Lingus, this was one of my better overseas departures from Boston Logan.
