Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

8.0 Very good

Jeremy, Feb 2026

The boarding was cumbersome. The staff was not aligned. They called group 1 but then the agent said no. Then they called group 1 again but still would not board us. Then they called group 2 and they all came up and still hadn’t started boarding. Then someone came from the plane and said why is no one coming? And the agent said bc i thought not yet and she said I said over the walkie talkie to send the passengers down? What was not clear about that? Also, onboard, the crew gave announcements very ironic/authoritative, and in first class they gave us a cheesebox. My expectations based on competition airlines, is a warm meal. A little underwhelming.
