Its been a while since I flew CO. I just booked a HKG-EWR , however the only flight avaible was a HKG-NRT-EWR on the inbound. The HKG-NRT is operated by ANA!? I guess this is due to CO joing *A, but when I booked the ticket it stated I need to wait 24 hours for them to check with ANA. This was all done on CO website.

Just want to know if this is normal, and want to make sure that the ticket will go through without a problem.

Thanks!
