I don't know if many people realize this, but you can use google.com to search which airlines fly between a city pair. For instance if I wanted to find flights between Bangkok and Columbo, Sri Lanka, I would simply type "BKK-CMB flights" in the goggle search bar. The results showed me the airline, the departure/arrival times, the flight numbers, and the days of the week a particular flight runs. This information was useful rather than searching the airline route maps or making a dummy booking. Now, google displays queries between city pairs with prices and the duration when the flight originates from the U.S. For city pairs outside of the US it sill displays the former search results. The latter information is almost useless. I'm going to go way out on the limb here and say that when someone types in "IAD-CDG flights" they're really not looking to buy flight per say, but rather more interested in the routes like it previously did. I think it's also safe to say that most people looking to book flights would just like to use one the more traditional OTAs out there than type in the lesser known airport codes to book a flight. Does anyone have any other way to search for flight routes between two city pairs or can suggest how I can voice my opinion with google.
