Irish budget carrier Ryanair estimates it will save €50 million ($65 million) as it progressively eliminates all airport check-in by October this year.
From 1 October, all passengers will be required to use Internet check-in and airport 'bag-drop' desks, as Ryanair looks to strip out what it regards as unnecessary airport costs.
Passengers will have to pay a fee for checked baggage, while Internet check-in services will be available 15 days to four hours before scheduled departure time.
Speaking at a briefing in London today Ryanair chief executive Michael O'Leary said: "We will simply give the keys back to [London Stansted and Dublin operators] BAA and DAA for check-in desks.
"We will have it down to one agent or baggage person for 10 flights at a time. We'll reduce our baggage crew from four to two per flight. The real target here is airport handling costs."
Ryanair will probably reduce check-in staff at Dublin Airport from 80 to 20 personnel.
