Registration B-2473 strongly suggests a late-service Air China passenger 747-400. The livery and Chinese flag confirm airline identity.

United's 777-200 fleet includes variants with both Pratt & Whitney and GE engines; Star Alliance livery jets serve as flagships for code-share branding.

The registration number C-GNBN and the TCA maple leaf logo confirm this as Air Canada's heritage 737 MAX 8.
