Speaking as a passenger, the right solution is CATOBAR. Passenger airports should install linear motor catapults that can get a 500-ton aircraft up to Mach 0.85 in about 10 seconds. (it can support the plane, allowing launch with already-retracted gear) They should also install arrester cables, or something better, such as a moving platform that could handle both tasks.

A much cheaper solution is just having really long runways.

That doesn't really work for Monaco, Vatican City, or Gibraltar. War is not cheap.

There is no reasonable way to expand London City Airport. Bulldozing London's financial industry to make more room for runways would mean bulldozing the primary customers.

Also, as a passenger, I just want CATOBAR.
