My sister and her family will want to go to Delhi, from YVR, on a consolidator fare - this winter. Of course, they would prefer to go on an airline with the best amenities, in the economy cabin. I know that Singapore Airlines offers PTV in economy class (I do not know if Cathay Pacific offers this amenity and/ir whether it flies to India, from Hong Kong).

There are (East) Indian travel agents in Vancouver that offer consolidator fares to India (I am not sure if they offer good fares on the above mentioned 2 airlines); I am wondering whether a Chinese travel agent may offer a better fare, esp via one of the 2 airlines mentioned above.
