Scenario:
- User is from city X
- There's no airports in X
- We have airports in nearby cities(A,B,C)
- Suggest user cities(A,B,C) to select in order of distance from X (asc) with distance calculation to airport
Suggestion should be done as helper.
Add universal controller action that bind user's geo as he specified his country/city/region to A/B/C. Action should fire an event(maybe for statistics collection).
