Regular airlines vs low cost airlines

Ever wondered how do low cost airlines manage with such cheap air fares?

1. Low cost aeroplanes have more seating capacity than any regular airplane of same size.
There is no business class and the distance between the seats is decreased to incorporate more
sitting space.
2. Low cost airlines dont server food which is usually of 5 star standard in normal airlines.
3. The staff (airhostesses, ground staff) are lesses in no. for low cost airlines.
4. Normal airlines have to pay more parking/taxiing charges. i.e suppose there is an intermediate
hop. In India normal airlines wait for 40 min before taking off where as low cost airlines fly
in 20 min.
5. Low cost airlines are open for advertising. For ex in Air deccan, usually every available
space carries an advertisement. The have tie up with Cafe Coffee day for selling snacks. Some
on the deccan planes carry Wipro Logo.
