DTV are very GA friendly!!!! If your aircraft is below 758kg then handling is free. I think they want business hence the small handling! landing fee's for a C152 is 11.49 which is average, even cheaper for a regional airport.
It's mandatory handling for all visiting aircraft regardless of weight.
It's good to see a positive side to DTVA.
for Midwest who provide one of the best GA handling facilities at a very low cost.
Being based there, I can only agree that ATC are very GA friendly and provide a service second to none.
