Kuwait

Hey everyone, We bought a ticket a month ago on Trip. It was supposed to be a flight leaving at 2:30 AM to arrive in Kuwait at 4:30 AM to catch a connecting flight with the same airline (Kuwait Airways) at 8:30 AM the same day, arriving in Paris at 12:45 PM. But Trip just informed us that KA "modified" the first flight to depart at 1:20 PM, which means we’ll miss the second leg of the journey. No alternative offered for that portion. After checking, the only solution is to take the flight the next day—so more than 17 hours of layover. We have to go back to work the next day, even though we’d planned a rest day. Trip’s only options are to cancel or accept the change!!! We asked them to propose an alternative flight, but their response was to contact the airline. We did, and their answer? Wait a bit longer for the final schedule!!! From my research, this counts as a cancellation or at least a delay of over 3 hours, so the airline is obligated to find us an alternative flight and compensate us. Has anyone had this experience with this airline or another? Any advice? Thanks in advance
