British Airways will reinstate Gatwick to New York next summer, initially as a Summer Seasonal. Gatwick to Orlando has also been been made twice daily from Gatwick for next Summer. If the
Heathrow Summer flight continues that will be 3 daily London to Orlando next Summer. However the thrice weekly summer seasonal Gatwick to Las Vegas I believe has been removed.
At the moment Summer 2022 is looking like BA Long Haul at Gatwick will need 12 based 777. This compares with 15 in Summer 2019. Still some way to go but a steady recovery from 2020 and 2021.
