Airplane types are not unique in flight results

[bauerj]

Google Flights shows which plane is planned to be used for a given flight. However, this in not really precise as one plane could match multiple planes in Atmosfair's API.

For example:

• Flight QR 816 is shown as flying a Boeing 777. Atmosfair however distinguishes between Boeing 777-200, Boeing 777-200LR, Boeing 777-300 and Boeing 777-300ER.
• Flight AY 99 uses an Airbus A350. Atmosfair knows the Airbus A350-1000 or Airbus A350-900

It is not clear which plane should be used to calculate the specific emissions. Currently, no plane type is sent in this case which results in a higher margin of error for the emission estimation.

One possible solution is to use the flight number instead of the planes type. A request with flightnumber looks like
{ "accountId": „...", "password":"...", "flights": [ { "flightNumber":"UA988", "departureDate":"2018-10-03", "passengerCount": 1, "flightCount": 2, "travelClass": "B", "charter": false } ] }

If no response is received or the response is insufficent it is okay to approximate or more precisely use the current logic.

For the current case a mapping is a better solution than to use no planetype. I will add a mapping to the current candidates.
