i am currently sitting in an airbus at the ahemdabad airport, on a hopping flight connecting baroda and new delhi. The flight took 20 minutes to fly from baroda to ahemdabad. And there are around 10 to 15 passengers who got down here: yes, they boarded a 20 minute flight. If you calculate the time the plane was stalled and taxied to the runway and the security clearance, it takes around 1.5 hours to travel from baroda to ahemdabad. If you go by road, it takes around the same time by the express way. A private taxi costs 3 times less. A coach costs around 10 times less whereas a bus or taking the train would mean around 18 to 20 times less. Add to that the fact that the airport will be farther from your home than the bus stop or the railway station. I dont really see the point in the 20 minute flight even in terms of time other than the eye pleasing stewardess.
