I was wondering what constitutes a "stop" on an airline route. For example, LGA has this 1500 mile radius rule (except on Saturday) however you are allowed to serve for example Austin if you stop at Houston en route as I believe CO does?
My question is how long does CO (or whoever) have to stop for in HOU for it to count as a stop? For example HP want to fly non-stop from PHX to LGA is the same way that UA can from DEN. My understanding is that they can do this if they stop at say STL (is that a logical stop??) en route and then continue to LGA.
However do they have to let passengers off at STL or could it be a "technical stop" where the passengers remain on board. If the later, does the plane have to pull up to stand? If not, does it in fact have to stop or could in land, taxi off the runway, taxi on again and continue on its way to LGA having "stopped" at STL. If this is the case then finally would it be possible to say just clip the runway and take off again (if that is actually possible) in a sort of VERY late aborted landing.
If they could do that, it would be SUCH a cool flight to be on I'm sure they could sell loads of tickets just on the novelty value.
