So basically I have booked a ticket from Aberdeen(UK) to Bangalore(India) on British Airways. The itinerary seems to be a bit tight now that I analyse it. I fly out from Aberdeen in the morning at 6 20 am and land in London Heathrow at 7 50 am, on BMI which is a codeshare airline with BA. This arrival happens in Terminal 1 of Heathrow after which I have a connection 1 hour and 40 mins later from Terminal 4 on Jet Airways. I am concerned that this much time isnt enough to travel between the two terminals given all circumstances such as delayed flights, late landing, unavailability of shuttles etc. I assume that this will be a through check in all the way till Bangalore, so baggage shouldnt be a problem. But has anybody been in a similar situation before, and if yes, any advice would be really helpful. Thanks in advance!
