1.Unlikely to get all BP at YQF (Red Deer). While YQF is a departure control system compliant station, the gate agent will have to complete an EDIFACT checkin (shift+F12 from the main checkin screen) for the ANA segments and they are unlikely to see this very often. Even if they get EDIFACT checkin, ANA system might refuse the checkin because the last segment (NRT-SIN) is not open for checkin due to being more than 24 hours prior to departure.

2. As stated above, no go on the F priority sticker. As for checking bags through to the end. Should be possible as AC DCS system can print out bag tags independent of checkin with final airline.

3. The AC agent at YQF should be able to get your UA BP, which you can use to get past UA checkin counters. However you will have to pick up your luggage in YYC and take it through US CBP. The luggage belt for USA connections is immediately after the Commissionaires look at your BP at the entrance to US CBP (don't go to the domestic bag belt on the arrivals level, instead the connection belt is part of US CBP on departures level). Look to your right as you pass the NEXUS line up entrance. Also on your left is Transborder duty free.

4. If you need to see UA checkin at YYC, this means the AC agent in YQF could not produce both the BP and Bag tag for the UA sector. In this case your stuck in YYC. There will not be enough time to walk to AC domestic bag claim. get you bags, walk back up stairs to the UA booth/checkin and make UA 1 hour checkin cut off.

Under this worst case scenario (e.g. you miss the UA flight) you would have to back to the AC ticketting desk to get a FIM (Flight Interruption Manifest) and get protected on either AC009 (YYC-NRT n/s) or AC207/AC003 (YYC-YVR-NRT) . Both the AC reroute optioin get you into NRT at the same time as the ANA through SFO. I would chose the one stop through YVR as AC003 is the 788 with better J class product.
