Some information regarding the British Airways Galleries Lounge PP option in EWR.
The lounge is located in the middle concourse of Terminal B, the B50 series gates. The airlines that use these gates in the morning hours are Singapore to SIN and Porter to YTZ. Occasionally Jetblue will run some international flights from these gates too. Other Terminal B airlines with morning flights are from the other concourses.
You can enter the B50 area, even if your flight is not from the B50 area, just did it this morning no problem. The TSA agent said he has seen people go through for the lounge or for other dining options. Just note there is no walkway past security to any other concourse, so you will need to redo security at your assigned area.
Lounge is really spacious and quiet at this time of day, considering it’s most useful customers are Porter Airlines passengers to YTZ. There were maybe about 5-6 people in the lounge which is very spread out.
Not much in the way of Kosher, there is some Rold Gold pretzels with OU and some Lays chips, as well as drinks. Wifi works great and fast and there are nice views of the runways from the lounge.
Hope this is helpful for someone passing through.
