Transat operates for three months out of the year . Being December,January,and March. So December is the only month that u can use this rebooking in. Most people will lose there money they paid . I thought that Transat air having a reputable would have allowed booking up to Apr.
Transat airlines will not refund Cancelation in wake of government advisory no avoid non essential travel outside Canada. They should have to refund . But, what is worst is they offer to let u Change date for free . U must be able to book and finish the trip by December 31/2020.
