I have to travel to Sao Paulo for business in 10 days. I have options (with around a $100 fare difference) to fly on the nonstop UA flight from ORD to GRU or fly Air Canada via YYZ.
I have flown the AC 767 product from YYZ to SCL a few years ago and loved it. I have not flown the 77W before (ever, on any airline) which is used from YYZ to GRU at this time of year. I know that UA is using the new-configured 777 on its nonstop flight from ORD to GRU, and I will have access to Y+ seating because I am Star silver.
So, anyone want to provide me a high-level pros and cons list?
