How to get your money back
EasyJet says customers whose flights have been cancelled can get either a full refund, a voucher for the value of their original booking, or an alternative flight of the same price.
The airline says affected customers will be contacted to discuss their options.
If people wish to get in touch themselves, they can call 0330 365 5000, but are being warned to expect long delays.
They can also manage their bookings online.
