Have flown VS from BOS-LHR on two recent
occaisions. Both times the service was great. They actually made you feel that they were glad you were there. Entertainment is far superior to US carriers. The food was good.
Would fly VS over UA, NW,AA,US,BA etc.
I fly UA in USA but to European continent
I fly LH. NW isn't bad either to Europe but to London I would prefer VS
