A CSR called and left a voicemail for me that I really didn't need to fly SFO-HNL-LAX-SYD-MEL-SYD-LAX-HNL-SFO. I could actually fly SFO-SYD-MEL-SYD-SFO and they would be happy to change the flights for me.
She even listed the new flight numbers for my convenience. All I could do was laugh.

Of course I checked to make sure nothing was touched on My Itineraries. Frankly, it sounds to me like they need the space. I just checked the outbound flight and it's F9, P9, A0, Y6, B6, E6, M6, U4, H4, Q2, V2, W1, T0, S1, K1, L0, G0, so the back is looking pretty full with more than a week to go for the flight.

Needless to say, I'm not returning that call.
