Catching an earlier flight
Good day.
I am flying FRA - ZRH - YUL. Currently on a 1030 departure from FRA to ZRH. Will Swiss allow me to catch a slightly earlier flight in the morning if I check in a bit early? Would like to get on the 0900 if possible to allow a bit more connecting time in Zurich.
I am flying in J from FRA and connecting to F from Zurich.
Thanks for any advice.
