Business class ticket to London for $5000 too good to be true

I have been offered two business class tickets to London next march for $10,000 by an overseas agency that specialises in discount premium seats. Any advice about this? V. Branson, Waterloo

Tempting as it sounds, I wouldn't.

There are several of these agencies that offer cut-price business class tickets and they all work the same way, buying points from flyers who have earned them legitimately and re-selling them to travellers in the form of flight bookings.

This contravenes airlines' terms and conditions.

Plenty of travellers get away with it but you don't have to search far on the internet to find tales from those who haven't.

If you don't, you'll be left at the check-in desk with a useless ticket, and the agency that sold it to you won't necessarily gallop to the rescue.

TIPOLOGIST

If your hotel room isn't up to scratch, if the airline loses your bag, if a tour operator doesn't deliver, document their shortcomings. Take photos, get the facts in writing and take down names. If you need to seek compensation, records will ease the process.
