The context here is that im a recent dual Canadian-British citizen (living in the UK) and generally would travel to the UK on my UK passport, but my NEXUS is, of course, attached to my Canadian passport (although they do have my UK info as of my latest renewal, which is pending), and am flying YYZ-LHR. As far as I know the UK does not require citizens to fly on their UK passport to the UK, but I certanly would prefer to.

So I'm not sure which I should do, as I have a few options:

• Enter my Canadian passport and PASS ID during checkin, use the NEXUS security line, and enter UK border control with my UK passport, or
• Enter my UK passport and PASS ID during checkin (is this even possible?), use the NEXUS security line, and enter the UK on my UK passport, or
• Enter my UK passport and no PASS ID during checkin, do not use the NEXUS security line, and go through UK border control on my UK passport.

I suspect the right answer is probably the first one, but seems prudent to check...
