British Airways Lounge: Opened in early 2017 in Terminal E of BOS airport. It has floor to ceiling window overlooking the Boston bay. It offers a hot buffet with a variety of hot entrees, as well as a full bar with Champagne. It also has capability to board directly to most flights.
We were able to use this lounge from an invitation of the Cathay Pacific Airways because we hold a Cathay Pacific Business class ticket. I know others were also able to access this lounge if you fly business with Japan airline as well. When we entered the lounge, it was pretty empty since it was around 11pm and our flight was schedule to leave around 1:45am on Cathay Pacific.
We had been to the old British Airway Lounge and this one is way bigger and more modern than the old one. Here are some pictures for you to enjoy. Visit this lounge if you could. It is definitely a plus if we have a chance to visit it during the day time.
