I agree helihub.
Whilst Heli Air may give "over 100% service and value for money" (I never could work out the phrase "over 100%"), let's not get carried away here.
I'm sure they'll give you the best service possible as they take your £469 + VAT A109 fee for landing... and the same again for taking off post race... and £105 + VAT for parking... and £150 + VAT for handling...
Yes Silverstone will take their cut, but £1193 + VAT???
Service with a smile should be guaranteed!!
