 Regional airports , such as Edinburgh Airport , have experienced strong growth in CAT operations in recent years . These operations are commercially and operationally incompatible with GA , and although there is no evidence of deliberate discrimination , the effect has been to discourage or exclude it . GA aircraft are being subject to significant increases in charges , including the imposition of handling fees in some cases . Some airports restrict or deny GA parking , and others limit or refuse certain GA activity . As a result , light GA aircraft are now rarely or never seen at large , busy international airports such as Heathrow , <unk> , Gatwick and Manchester .
