Yikes! However I just looked at the EWR-YUL flight and already 3 FC seats are gone and 8 out 12 Preferred seats and not a single reg coach seat. I wouldnt be surprised if most of those folks are connecting onto my flight. The trip is in Oct and PE and Biz are long gone as with the YYZ flight to TLV. This year if you dont fly out by the Sun of that week then its that Thurs or basically not at all unless you fly UA or LY on their non-stops

I guess it may come down to how many late connecting passengers will AC wait for, then again maybe those folks are heading elsewhere but I doubt it

FWIW I just checked the 10:40am flight no FC taken and only 1 Preferred no reg Y, guess no one else wants a 6 hr layover if they can help it, the only bad thing is if the flight isnt held then thats close to a dz people looking to get rebooked onto 1 of 3 flights to arrive in time into TLV and flights are fast filling up so they may be soldout on that day and no rebooking
