As I said, flights are only cancelled as a last resort.
Being based in East Mids airport myself, I know of in the last week, that crew have been sent to Bristol, and Gatwick.
One crew member that I know of was sent to Gatwick in a taxi the other day, took well over 3 hours to get there and with is being a friday afternoon they were caught up in some heavy traffic on the way back, it ended up that they spent more time in the back of a car that day than they did actually operating onboard an aircraft.
I know nobody likes it when flights are cancelled, especially passengers, but as mentioned before easyJet are doing their very best to keep flights operating as normal (by taxiing crew left, right and centre) some flights have even been chartered out to other airlines.
