Good day. Me and my brother in law has made a reservation dmm to dubai on 21 may 2021 flight number fz 866 depature at 09:00 .This reservation was made on 19 february 2021. On march 31 2021 we have recieved an email from flydubai advicing us that they have cancelled our flight for what reasons!? we dont know but for sure we didnt ask for any changes. And they asked us to rebook again another flight " that simple" now. What fly dubai has done is wrong, in any other respectable airline they rebook your flight free of charege or refund your money for the flight cancelled and rebooke you a new flight, but again that only on the respectable airline the other mistake fly dubai made is that the cancelled booking cost is higher than the newly priced booking, so where did the diffrence in the price went to ?, this action is unexceptable, and we will raise this issue to international civil aviation organization, and to iata, and to the proper authurity in uae if i dont recieved a respictable compensation me and my brother for this act
