Hello Sasha...
We are very happy to hear that your husband has recieved the passport. I am also from vancouver and the good affordable flights that I have flown on have been CI China Airlines, CA Cathay Pacific and I am not sure if he is allowed to come over the atlantic for the first time, but if so, then Lufthansa is also very good. Last week I checked with CI and the price was 32, 000 Rs one way, and their bagge limit is 2 and 23kg each, plus they also have good extra baggage policy, thats why I choose to go on that. Check another one JAL, they sometimes have sales for DEL to YVR route.
I wish you both the very best in your future and take care.
