Areed HM. It's all the same. It's called Two Tier Pricing and goes back a hundred years or more. Humans have become focussed on the 'striking price' and if that is lower - they are more likely to be drawn across the shop threshold be it actual or virtual.
It is why products are advertised at 9.99 and so on. So there is no chance of this kind of action going away - it will simply change. There did not used to be Booking Fees (especially when we have done all the work as RAT 5 states) so they will invent something else. If they put .50 on each ticket and call it inflation, they would proabably make more. I started the thread more as a general point than any kind of 'good news'.
