Your mistake is listening to the incredible garbage Einstein spewed.
The time to walk from London to New York on a plane is equal to
the time it takes to return from the flight deck to the tail.

the "time" required by light to travel from A (London, tail of plane) to B
(New York, flight deck) equals the "time" it requires to travel from B to A
