Will be flying out of YQB on AC tomorrow and another family member departing on UA. Is everything in one terminal or is there a barrier between terminals. Best I could tell from the website is that everything is together.

Also, we have a 4 PM flight. Does AC have a maximum time they will check luggage in at as we will be trying to do a same day confirmed change at the airport to an 1130 flight. My understanding is they will not check luggage more than 4 hours before the confirmed departure and we would have to be confirmed on the earlier flight for them to check our luggage.

Thanks in advance for your help!
