I arrive at LHR at 10:10 am on March 31, 2022, on DL #3 (from JFK). I think arrival is T3.
I need to calculate which train at T2 & T3 to take via King's Cross to Cambridge? With no checked luggage, do I need to allow for more than 1 hour from time of expected arrival from USA after customs and Covid test check?
In 2012, I arrived at LHR on DL then took a bus to Oxford and the walking time after customs was at least one hour, I think.
I return from Cambridge on the following Sunday using the same train route. Once back to LHR, is the Renaissance London Heathrow Hotel not close to the train arrival T2/3?
