There are plenty of things to consider when traveling on a plane that are different from when traveling in a car or other mode of transportation.
 This mini-series was just an overview and still only the tip of the iceberg.
  There are other rules to checking in special items like firearms, skis, golf clubs, boxes, strollers and anything else that may not be in a suitcase.
 Security measures change all the time due to a change in rules or some event that may elevate the risk level.
 There are people in wheelchairs or people with certain allergies.
 There are delays and cancellations or mechanical situations that may change baggage requirements or the number of seats available on a plane.
 There are weather issues that may be in another city that make a change in your plans or in the city you are in.
A good rule of thumb is to always call the airline about one week before your departure to make sure there have been no changes.
 Then also call the day of your departure to make sure there have been no major changes or delays   The one thing you can always say about traveling is it's always an adventure.
 Of course when you plan a vacation, that's basically what you were wanting was an adventure.
    Maybe this mini-series gave you some good tips that you may be able to use on your next trip or at least a better understanding on how you may be a little more prepared so you have a good time.
 Hopefully your traveling experiences will always be enjoyable and on time and above all, you have fun and are safe.
