I Will Be Travelling From Hyderabad In India To USA enroute Heathrow Airport In London. I Have 1 Hour 55 Minutes Layover Time Between The Flights. I Have To Change The Terminal From 3 To 5 To Board The Plane To Usa. Will It Be Sufficient For Me To Board The Plane?
Is this a single booking? If so it will be tight but the airline believes it can be done.
If you have one booking ( ticket) from India to LHR and a separate one from LHR to the USA you are at high risk for a disaster
That is enough time to make your connecting flight as long as the flight from Hyderabad leaves on time; please say what airlines are you flying to get a clearer idea here.
British Airways
Single ticket from Hyderabad to USA and travelling by British Airways
As long as you arrive at LHR reasonably close to on time, you should make it. You will be on the move the whole time and if fortunate will have time for a bathroom stop once you get to your departure gate.
