Connection time in London

Probably. If you say what your connection is, and whether it is a single booking it should be possible to be more definitive.

Depends on where you are starting from and going to. For example, if you are flying into Heathrow on American Airlines, you will be arriving at Terminal 3. Is your connection departing from Terminal 5 (which would be British Airlines)? If you are, two hours is not enough. Why? You will have to transfer, by bus, to Terminal 5 and go through security again before going to your gate. That security line can get very long. It's really a crap shoot on the length of that line. Check online to see what terminal you are landing in and what terminal you are departing from. Have a great trip!

Right now it is actually 2hr 20min. The flight originates in Athens on British Airways - final destination Boston. Right now it looks like they are both BA flights going into and out of Terminal 5. I know they code share with American, but neither appears to be an AA flight. So we should be good?

Thank you!

Relatively straightforward, only a security/hand baggage check to go through.

Great, thank you so much. Now let's see if I can still get the fare!
