Denied

I’m a little upset with Air Monopoly right now.
I get a lovely email this morning talking about a seat sale. Since I have a resort in Jamaica reserved for November, and I just need a flight, I thought I would check it out.
Why yes, that is a good deal.
So this evening I started the process of signing up. I give them all the information they need, and in the end they snub me. I am not using an approved computer. They don’t support Mac OS X.
It’s been a long time since my choice of OS was snubbed. I’m not used to anymore.
