I thought I had a pretty good handle on this topic. So much so that I have a side hustle (unpaid) advising friends how to avoid sleeping on airport floors during disruption. But this one has me stumped.

We were all caught up in the storm that hit the Balearics end of August. I managed to sort myself out. A friend could only get rebooked on BA or even another carrier the following Wednesday (this happened on a Sunday), so I told her not to cancel the ticket and we found an option on easyJet connecting through Geneva on the Monday, which she would later claim back. She used one of those sites where you can actually book a connection on easyJet (I guess they charge extra for insurance in case something goes wrong).

She managed to get to Geneva no problem. But then the onward flight to Luton got cancelled. So she then - without my approval - just booked herself a very expensive flight to London on BA. Had I been there, I would have recommended trying to get BA to book this directly. But there it is.

So wondering how to proceed with this. Does it make sense to try and get the whole lot from BA? Or is it best to try and claim the easyJet flight from BA and then the GVA-LTN from easyJet?

She's so far had a reply from BA after trying to claim the lot saying they are not liable for anything, but as a gesture of goodwill, they are reimbursing a night's hotel in Palma. Obviously this is wrong as duty of care still stands.

Any recs on how to handle this? I don't think you can use CEDR for easyJet if it comes to that.
