You had a much more fortunate and positive experience than we have to date. We depart in September and our return flight was cancelled in May, Flights by Celebrity told us it would take 10 days to resolve so we went ahead and made final payment. Multiple calls by our TA and they kept sending confirmation of the cancelled flight (with an outdated booking reference number). Finally, 2 weeks ago got another notification that our flight was cancelled but still no alternate flight. Interestingly, our reservation is linked to our friends' reservation and they received their alternate flight over 3 weeks ago. And, on top of that, our flight to Venice on BA still hasn't been ticketed and we fly out in 41 days.
