Hi Debbie.
Someone from customer service team will be giving you a call about your queries. In regards to our flight seats, we allocate a certain amount of seats for each tour from each airport, and these seats usually cost more than the main London airports - hence the regional flight fee. Unfortunately there is no more availability for flights from Birmingham airport.
I hope all of your questions can be answered by our customer service team, and if you have any further questions, please let me know and I will look into it for you.
Kindest regards,
Monty
The key word there is 'usually'. I would like to suggest you charge the actual difference, including passing on any reductions in price for flying from regional airports and not set a blanket increase under an assumption that it will cost more.
I travelled from Birmingham in October via Paris on the Chile, Argentina and Brazil trip which cost £69 more. Seeing as the actual airline used for the leg was a budget airline, an Air France codeshare, I checked out the fares when I got back and found out they would have been £30 cheaper than Heathrow's equivalent Air France flight booking direct (including after a 23kg hold bag charged as an extra) - so was absolutely fuming that I'd effectively been charged £99 more than I should have been for an equivalent margin take for the company compared to those flying from Heathrow. It's these kinds of sharp practices that really annoy customers.
Not that I ever need it as an independent person and traveller (but I fully understand that it's part of your service for those that need reassurance), but there was no Just You meet and greet person at check-in as I was the only person flying from BHX, so it wasn't extra money used to cover their wages either.
