Looks like there was a minor change to the class drop down?
IIRC it used to be:
Basic Economy
Main Cabin
Delta Comfort+
Delta One
Now it shows:
Basic Economy
Main Cabin
Delta Comfort+
First Class
Premium Select
Delta One
Also, I have an award booked 3/4 SYD>CAN>HND on CZ, that I booked via DL.com. I was curious today if there was a price change on it, and DL.com doesn't show any routing SYD>TYO available. Anyone else having an issue? Seems similar to the China Eastern one above.
