Maybe they will continue, but management "rumour" is often a way to let the staff get used to the idea in principle:
In a letter to BA staff at the complex south of London, seen by the FT, Adam Carson, managing director of BA Gatwick, wrote: “As you know, we suspended our Gatwick flying schedule at the start of April and there is no certainty as to when or if these services can or will return.”
In a process called “Preparing for a Different Future”. British Airways wants rid of 12,000 of its 42,000 staff. The figures set out by the airline in letters to trade unions reveal that BA envisages 22 per cent fewer flights when aviation finally gets back in the skies.
"Many services to and from its main base,
Heathrow airport, will be culled. This, though, creates a problem. BA’s most valuable asset is its slot portfolio at Heathrow. In normal times, a strict “use them or lose them” rule applies for the precious permissions to take off and land at Europe’s busiest hub. Moving most or all flights from Gatwick around to Heathrow provides a solution."
I for one would like BA to continue at LGW, it's been a cornerstone for years, and the airport are still pressing ahead with the planning to convert the emergency runway for full time ops..
