As a working airline pilot who has flown out of LGA (LaGuardia) extensively I feel a need to comment on Biden's remarks calling LaGaurdia airport a third world facility compared to China's shiney new international airport. LGA was built when planes went 150mph and needed a 3,000 foot runway. Being on the edge of Flushing bay it has no place to expand. In fact when the runways were extended to accommodate faster planes (jets) they had to be built over the water (a good part of the runways is actually an over water bridge structure). There is simply no place left to expand to. The field only has 2 runways to accommodate more traffic than JKF (where I still fly out of). Even if you ironed LGA flat and designed a new airport from scratch, there is no place to put bigger facilities or more runways as the airport was never intended to deal with the kind of traffic is sees.
At nearby JFK they have built 2 brand new terminals with a third under construction and put in a billion dollar air train. It should also be noted that LGA is a domestic airport that does not handle widebody aircraft so it is unfair to compare it to a major international airport. You might as well compare Hong Kong or Tokyo to Chicago Midway or Jacksonville, Florida.
Another issue is that an airport has to operate while new structures are built. There is an old joke in aviation that an airport is a construction sight with a runway. Temporary terminals have to be constructed while the permanent ones are built. There was actually a televised documentary of the construction of Jetblue's temporary terminal (which was used for a few years while the new T-5 was built). This takes hundreds of millions of dollars and airlines that are willing to commit to the new facilities. Since Jetblue is in the middle of building a new international terminal (T-6) at JFK they can't do it. American, United and Delta are already paying through that nose to be at LGA so they can't do it. So who is going to pay for it. Should be around half a billion.
New York (and many major American cities) have airports that have grown since their original pre-WW2 construction and they have had to make due. A few cities like Denver actually bit the bullet and built brand new facilities but it is expensive and not to be done lightly. Some new airports have been built only to be underutilized (ex: Panama City FL). Some had room for great expansion (ex: Orlando FL MCO) but many are built in cities or by waters edge greatly complicating expansion.
Additionally China (and in fact most countries) have only a few major cities. America has dozens and many have kept up with modernization. Airports like Orlando, Tampa, Miami, Chicago, L.A., Seattle, Denver, Boston and even Detroit have kept up (often against major difficulties). Cities like San Francisco (SFO) and Washington DC (DCA) have great terminals but lousy, even dangerous airport layouts. DCA has dangerous southern approaches and northern departures via the Potomac River (to avoid overflying prohibited area P-56 near the white house and the mall) and SFO's runways are too close together. Yet despite these dangers officialdom has chosen to just leave it alone rather than spend tons of money to fix it. As an aside, the DCA issue could be fixed with the stroke of a Presidential pen allowing flights over the mall. I have only scratched the surface here but Biden's comments are not simply fair. LGA is a hard pressed local airport for narrow bodied jets and commuter planes and comparing it to China's showpiece major international airports is like comparing the family station wagon to a yuppies BMW.
