Hi folks, my sister booked an Aeroplan reward flight all on one booking reference:
SQ - SIN to CGK
EY - CGK to JFK via AUH

I could not find any info on SQ and EY having an interline agreement.

Questions:
1. Is it possible to get the bags tagged all the way to JFK?
2. If not, is there a way to tag the bag to CGK, pick it up and check in at EY without having to pay for a visa? As a Canadian, we need to get a visa if visiting Indonesia but she is just transiting. I’m afraid she may have to pay one.
