This will be my first time flying into Canada, I have my passport no problem there, but have a few questions about flying UA (first time on E170, got 3A each way):

- I assume that I can still check-in online, but can I still use the united.com bag check in T1 to check bags? (Not sure but my guess is I may be flying out of T2)

- I understand that I will have to go through customs and immigration when I arrive in YUL, will I have to go through anything besides regualr security when I depart YUL? I would think so since I know I won't have to go through customs/immigration when arrving back at ORD.

- Anyone have any experience going through YUL security? On my return flight I leave at 6am so I imagine that it will be pretty empty when I arrive, I assume the UA counter opens at 4am or so.

Thanks
