So, no BPs can be issued online or in the app for any AUH-US flights? Only obtained at check-in, it seems.
The "2/4 passengers checked in" seems a rogue message, as we got the same message for our return flight. 4/4 passengers checked in online and BPs issued for JFK-AUH and AUH-MCT, yet the app says only 2 passengers are checked in.
