Interesting thought about the return to LHR .
Almost all BA guys would naturally return to LHR , somewhere they know , maintainance , pax handling , car in carpark and so on . However .... how much better to lob into Stanstead ..... disrupt fewer passengers , cost only competitors and save £££Millions on LHR closure. Excellent fire service and reasonable passenger handling and possibly nearer.
You have to wonder about the commercial aspects!
( Yes I know ...Safety is our number one priority ...)
