Why the comparison lives in the address bar
There is no page per pair of airports here, and there will not be. The number of pairs is in the millions, and almost none of them are something anyone searches for. Keeping the state in the query string means one page can serve every comparison while the index stays the size it should be. The distance calculator works the same way, and route pages exist only for pairs an airline actually flies.
