I fly Boston to Heathrow tomorrow morning and checked in online. According to the online system it told me the allowance for checked bags on this flight is ZERO. They wanted to charge me $60 extra for one checked bag. However, when I check the online details more generally on the BA website (ie: outside the online check-in system) it seems like even the World Traveller Economy tickets come with one free bag. What's the deal? Anybody traveled that route recently with info to share? If I can avoid having to cram everything for a 2 week trip into one cabin bag it would be great, so quick replies would be much appreciated!
