I'm using miles in my account to upgrade my girlfriend from Y to C JFK-SFO-LAX then LAX-JFK. Call the 1K desk to request the upgrade, 1K CSR said 30,000 miles will be deducted from my account, but when I went to my local airport to authorize the use of my miles the local agent took out 45,000 miles! I thought SFO-LAX is consider a connection within a segment and only one mileage upgrade award is needed. Who is right?
