Flights to London are to be affected after the Unite union announced British Airways cabin crew will strike.
Services to London City will be unaffected but there will be disruptions on flights to Heathrow and Gatwick.
Cabin crew will go on strike for three days from March 20, and for four days a week later.
BA say only around half of their flights to Gatwick will be operating during the strike and services to Heathrow could be minimal.
This could affect those connecting to long haul flights.
Unite confirmed it would not strike over Easter, but did warn of further action.
