I'm trying to book a flight from SYD->SFO for a few days from now. I can select my flights on www.unitedairlines.com.au and see prices, but when I try to book it says that it's too close to depature to book online.

The cost of the flight online is ~AU$1600, but when I call to book, it's ~AU$2200. Is there any way to get this price or am I out of luck?

The earliest I could book on www.unitedairlines.com.au was a week ahead. That seems like an absurd restriction, considering on ual.com, you can book the day before. Unfortunately on ual.com, the prices are similar to the phone prices.

Any ideas?

Thanks
