I am travelling from Seattle to Bangalore, India and back, a couple of months from now. I found this really good ticket on British Airways that i wanted to buy till i realized that the layover time is just 1h and 10 mins at London (Heathrow) while travelling from Bangalore, India to Seattle. I know my checked luggage will go on automatically and i do not have to do anything about it. But my concern is whether i will be able to make it through security in time. The last time i was travelling the same route, i had to go through security at heathrow on my way to Seattle. I am getting a really good deal on this ticket (will end up saving $300-$400). But am just thinking if its really worth it. it is really important also that i get back to Seattle on the day i am intending to land. It will be great if you could help me out.

Assuming this is a routing offered by BA, with two BA flights (Bangalore-London and London-Seattle), I have to believe it meets the mininmum connection times. Of course, all bets are off if the first flight is delayed. Although it's up to BA to rebook you if you don't make the second flight because of their delay, that's small consolation if you MUST arrive in Seattle on a certain day.

Some US airlines will give you data on how often a given flight is delayed, but don't know if BA does this? Perhaps try to Google "British Airways on time performance" to see if you can find information about this particular routing.

IF/IF the return flight involves two different airlines (or one of the legs is a code share using another airlines' plane) then I would indeed be concerned about a tight connection. BA will be helpful if the first flight is delayed (holding the second flight briefly, transferring you in a golf cart, etc.) only if both flights are on BA equipment.

Based on a previous experience we had when in Heathrow, I would be concerned if your luggage would make it there or not...we had a 90 minute layover once in Heathrow, and our luggage didn't make it until the next flight out after ours. Just another item to consider...I can't speak for the amount of time through security.

You can go to Travelocity and enter your route (as if looking to buy a ticket), select the British Airways options, and then "flight details." It shows you how often this flight is on time historically.

I randomly picked 10/12 for a travel date, and came up with a BA 118/BA 49 routing. (This has a 2.5 hour layover at LHR.) Historically BA 118 is on time 95% of the time; BA 49 is only 60%. If your flights are different than these, you can always enter them separately to get the on-time info.

As far as I am aware the minimum transit time for any 2 flights at LHR is 2 hours. If one airline is selling these two flights on a single ticket and you don;t make it -- it;s their problem to fix. If this is 2 differnt tickets and you don;t make it the problem is yours. You will be a no show on the second flight and whill have to buy a ticket for the next flight out at the (very expensive) walk up rate.

You seem to say your luggage will be checked through - which sound like a single ticket. I would contact the airline to be sure this is a legal connection and that your luggage will go through.

I have had to make connections at Heathrow numerous times - and there is no way i would ever have made any of them in this amount of time.
