| <5> | When we are planning a trip (for example, to Ontario), we usually look for the obvious: the choice of airlines that fly into the airport, the number of flights, the connections we have to make, which car rentals are available, etc. We also look for sights and attractions that we might find between any given airport and our destination - we do love exploring. We're willing to fly into a more distant airport if we can get the services and amenities that we like. Even though our choice of airport might be inconvenient to others, it usually gives us a better trip. |
