(svn r6770) -Codechange: Make the airport checking a bit stricter...fix unnoticed errors:
Commuter (20): invalid use of terminal group designator; since all other options
goto position 2 and no additional blocks are checked, simplify state
Intercontinental (23, 30): no extra states are needed since all options go to
position 70 and 31 unconditionally
Intercontinental (31): invalid use of more-options-to-follow (255)
