Following a search on Arriva's site and Goggle this is what I found (I don't know this area so I not sure if this info will be correct), the closet you can get to the airport is on Arriva service 12 which stops at Durham Tees Valley Airport Fire Training Centre which according to Goggle Maps is 7 minutes walk away. Don't get the 12A as that goes to Middleton-St-George.
Cheers
Might tell them to get the 12 then.
