No. flew AC7759--AC9--CA903 on April 30, 2023. My flight AC 9 was late for 2 hours and arrived at 17:30 PM. CA 930 took off at 17:45 PM (late too). But it did wait for transit passages from AC 9. Over 20 passengers had to sleep over at Toyko Hotel overnight, then took ANA to Shanghai in the morning. AC sucks.
At YOW AC 7759 check-in required the QR code and in Toyko ANA check-in required a QR code. My phone ( Fido with Rogers) only had a text message and phone roaming, no data roaming ( sucks Fido). I have no time to figure out why my phone could not connect WiFI in Toyko airport, so I filled out 海关黑码表 in Toyko Hotel again to get a new QR code since it had been over 24 hours due to AC 9 being late.
I have no problem taking a ride or public transport in China since I had someone to accompany me from the arrival airport to the departure airport ( Beijing). She scanned her watch to get in, then scan her phone for me to get in the subway. It worked in Shanghai and other cities but did not work in Beijing. She had to download another App in Beijing on her phone for me to get on the Subway or other public transport.
