In general, European promotions are more generous and run at different times.
For example, in the UK there is often a triple miles promotion in January which gives triple miles on FULLY FLEXIBLE Club World tickets.
In Europe, similar promos often run in October-November. They usually include the cheaper, inflexible Club World tickets which can be a great result - Ms Raffles got 60,000 miles 2 year ago for a £1,700 ex-Milan ticket to Bangkok.
