Which are the best airlines to take from Orlando to Barcelona, Barcelona to London, and London to Orlando? We would prefer to have one stop with each the Orlando to Barcelona and London to Orlando trips. The hop from Barcelona to London, we'd really like a nonstop. iEconomy is good, but decent facilities/planes and safety are more important. I doubt we'll go for the first class type tickets. We will be going in late August of 2014 and coming back in early September of the same year. Thanks!
