I booked two LONE4s for Mrs P and me on September 17th, through the AA RTW Desk. Rang back 24hrs later and was told the price.

Now this morning I rang AA in Aus to ticket and pay - and was told that the earlier price had 'expired' and it would have to be re-checked and I was to ring back in 24hrs or so

Is this the normal practice?
Scary for me, given the way the A$ has tanked over the last few weeks. I know the base ticket price is quoted in A$ and so will be unchanged - but it's all those +++ in other currencies that have me worried
