Can't understand how the budget airline business model works.
Perhaps some smarter or more knowledgeable chaps can explain.
Major costs that are similar to normal airlines:
-- cost of planes or depreciation
-- staff costs, e.g. pilots, flight attendents, ground crew, maintenance crew, cleaning crew, etc
-- recurring maintenance and overhaul costs
-- safety measures costs
-- advertising and marketing costs
Minor costs that are perhaps not incurred by budget airlines
-- food and beverages on board
-- costs to administer rewards program
-- costs to change bookings, reservations, etc.
-- costs to ensure timing of flights and customer compensation
Don't tell me the last item is the key which ensures that budget airlines can keep up with normal airlines, taking into account the lower ticket prices?
