I was searching fares to LHR next spring via SFO or LAX and VS is about $330.00 more than BA for PE vs. WTP. I understand VS seat width is 20.0" while BA is 18.5". Does the higher fare correlate to better service. I am flying VS this week from SFo to LHR in PE and thought about BA-WTP IAH-DTW-LHR-DTW-IAH in the spring...love the B763s. Your thoughts? Thanks. PAris Hilton and I have something in common, every inch counts(20vs18.5).
