Following ridiculous delays and insulting offers of re-imbursement in the form of "a complimentary upgrade to addition legroom seating on your next flight", I put an EU261 claim in to Monarch on 29th October. They have (after chasing and copying in the CAA) replied saying it's being investigated. 3 Months later and still no outcome from them. How long do they have to resolve these complaints as this seems a little inefficient.
