JAL will be using BA lounges (and agents) at BOS

Emeralds -> BA F Lounge
Sapphire/Business/Normal Fare Y -> BA Terraces Lounge

Looks like ground agents will be BA ones too according to photos uploaded to the Facebook page: https://www.facebook.com/media/set/?...3850783&type=1

Looks great, can't wait til I take it next month.

Makes sense as they are working out of Terminal E, the international terminal that BA uses, and not Terminal B which AA uses. Lounges should be completely empty too, no BA flights during the time of the JL flights. One morning flight before 9AM, then the rest are all late afternoon and evening. It is supposed to absolutely pour here in BOS Sunday, so I guess nature beat the fire department to the traditional water gun salute! :D

Do full-fare Y passengers get lounge access on JL?

I have never seen that before.

That has been the case for most routes on JAL

I guess it makes sense. The margins on full-fare Y can probably be higher than some cheapo business tickets. And it is probably a cheap benefit to offer, as all of the lounge infastructure already exists.


Do you know of any other airlines that offer this to full-fare Y passengers?

NH
