Do you know which airline lives at which city? Some of these have more that one hub city, unfortunately you can only enter one of them on here. Just go for the main one.
This is a good idea, but has WAY too many errors. “Canada,” “Prague,” and “Austrian” are misspelled. LA is my no means American’s main hub-that would be Dallas. Even so, you need to accept “Los Angeles.” Im also suspicious about Vancouver and Mumbai. (I believe they should be Toronto and Delhi.)
