Economy Plus Automatic Upgrade
I booked a roundtrip flight from LAX to Tokyo. First leg is on United, second is via ANA. As you all know, MileagePlus Gold and above get automatic upgrades from Economy to EconomyPlus when flying with United directly. Does this same perk extend to ANA and other Star Alliance as well? Basically, do I get the same upgrade privilege on the ANA leg as I do on the United leg?
Thanks.
