I know the most economical way of getting to Europe is to fly on AA metal & not through LHR. With that being said, BA does have much more availability & London is a place that we have not yet visited so if we were wanting to goto Europe (With London as a part of that overall trip) what methods are the most economical? Based upon my research (Plugging in HOME - LHR & Home -> Europe | Europe -> Home & LHR - Home) i've found that doing the following is the one that has the least amount of taxes/fees. Home - LHR Europe - LHR - Home Are my findings correct? anything else I miss?
