Well, it was worth a shot. I was thinking entry to Japan is still blocked for most, so maybe there's options. I did plan to try ANA First in winter 2022, but good to know 2 seats is almost impossible. We might have to fly one day apart, or from different airports then.
Is AirCanada or United better at searching for ANA First space? United is much easier to see, but AirCanada opens their dates earlier?
Otherwise, I see possibilities to go Turkish air or Swiss air to Singapore on business and can try one product there and the other on return. Are there any other interesting routings? Via Seoul with Asiana or BKK with Thai?
