A reminder that Iberia relocates back to LHR Terminal 5 (from the existing T3 arrangements) from tomorrow 1 June 2023.
The check-in desk area is Zone B desks 9 to 16, which is the North end (so nearest the Heathrow Express and the tube stations).
BA are doing all the handling except for loading and unloading bags and cargo, plus pushback, these specific activities being done by GH London.
