My flight to Gatwick is now cancelled. And EasyJet can’t fly me until Saturday night. And I have a reservation at St John tomorrow lunch time....I like a challenge!
The worst thing with these cancellations is that you get moved to the next available flight but, at busy times of year, there aren't too many empty seats on following flights so you can wait many days if not weeks to get a seat.
Given the time of year, Saturday evening doesn't sound too bad, restaurant booking aside.
