Pay by cheque, it will cost them even more!
I am intrigued - why would you want to " cost airfields even more"? Most are struggling big time at the moment & many smaller places haven't increased their £10.00 landing fees for basic SEP in over 10 years -despite the VAT increase. If paying by debit card costs airfields an extra 50p then which is more fair - to charge the card user the 50p or to put the fees up to everybody to so that the majority of cash payers subsidise the card payer?
