And of course reasons against it can include the quantity of luggage you have with you, the 200+ yard walk in whatever weather conditions exist, and any mobility challenges you may have. If what Diego's has posted is correct, it seems that a compromise has been reached between the involved parties to allow arriving airline passengers to catch cabs outside the airport grounds. Previously I had heard of occasional "crackdowns" to discourage the practice.The wait would likely be no longer than the time to walk off the airport and to the next corner. The reasons to walk out and get a taxi are to eat lunch at Diego's or to save a few dollars (probably less than $5/person). Or maybe to avoid sharing a van with strangers.
