There will never be a solution to this problem unless we stop people flying.
A good first step would be to stop converting a place intended to get people on board of an airplane into shopping malls and restaurants intended to make a maximum of money. Everytime an airport is "improved" the number of shops is increased, the distance to walk is increased, the time you have to plan to get to the plane is increased. (Last example I found extremely annoying is BRS, where they installed a large Duty-Free shop between security and waiting area, reducing the number of seats in the waiting area significantly, pushing the passengers into the restaurants. It once was a nice and simple airport, now it becomes the same as anywhere) Security is always second priority after profit. Most Airports make their money renting out shop and restaurant space, not serving airlines.
