Sorry, not sure where to place this thread...

The wife and I have an Easyjet flight booked for next month from CDG to EDI departing at ~4:30pm. Any suggestions on how to mitigate the risk of our Easyjet flight being canceled due to the ash cloud? We've got a B&B booked in Edinburgh that night and we have limited time in town so it would be optimal that we make it there by end of the day.

Obviously there a lot of unknowns but...
- We'll obviously check their website day of for any bulletins.
- Our backup plan is to train it thru the chunnel and up to Scotland. Just concerned about getting a refund from Easyjet.
- We'll also likely push back by a day a tour we wanted to take in Edinburgh
