Arnold,
I agree with your statement totally, They more than anyone would know that, and any other rules too.
So Nik, get in touch with the airline and demand a re-routing for your wife, and don't take any crap about you paying any extra charges for their blatant mistake either. Demand to speak with someone in authority if your not getting anywhere with the ticket saleperson. Theaten all sorts, if your still not getting anywhere with them, but always politly ..haha!! .....It rarely comes to that, but it has worked for me on a number of occassions. The best one, is that you work for a travel magazine...lol!!
David.....
