So based on my historic BA preference the travel agent checked prices, same flight class (Business) same dates 18th April out 30th April back
The Price for British Airways £4446.77, Virgin £2967.77, so in the midst of trying to keep passengers, and encourage premium pax back even in the uncertainty of further strike action BA are expecting a £1500 premium.....
I've just priced up LHR to BOS return for those dates in Upper class without Limo transfer - the Virgin equivalent of BA's club world product) for those dates and the price is £4412.77
Must have been a special fare.
