Why isn't the Google QPX Express API returning results for all airlines?
问题 I enabled access to the Google QPX Express API to do some analytics on the prices of Delta's tickets and Fare Classes. But the response seems to only include flights from a limited set of airlines. For example, the following request { "request": { "passengers": { "adultCount": 1 }, "slice": [ { "origin": "JFK", "destination": "SFO", "date": "2015-02-15", "maxStops": 0 } ], "solutions": 500 } } only returns flights for AS (Alaska Airlines), US (US Air), VX (Virgin America), B6 (JetBlue), and
