London Air Travel » British Airways »
British Airways is moving a number of short-haul routes between London Gatwick and Heathrow airports from late March 2019.
In addition, a number of routes that operate from both Gatwick and Heathrow will be “consolidated” at one airport.
No specific reasons have been given for the changes but it is likely to be due to a combination of commercial performance and operational requirements.
At the time of writing, it appears that not all online timetables have not been fully updated so it may be some time before changes show in the Manage My Booking tool.

Advice For Passengers
When routes transfer between Gatwick and Heathrow the flight numbers change as BA uses different flight number sequences at Gatwick and Heathrow. This means your original booking is effectively cancelled. If your flight is cancelled you have the option of a refund or rebooking. However, any consequential costs such as ground transportation will be at your own expense.
If you are connecting to or from a long-haul flight, it is strongly recommended that you look at alternative routings to avoid transferring between London airports. BA does not provide free transfers between Gatwick and Heathrow and this will be at your own expense.
For example, if you were due to fly from New York to Bilbao via Heathrow you could transfer your flight from New York to Gatwick. Or if you were due to fly from Boston to Almeria via Heathrow, you could choose to fly on Iberia via Madrid.
