Airport security has never been tighter and will probably never relax again. Unlike a hotel, where you can fuss and throw a fit and generally get your way, the airport security will detain you, search you, and make your life miserable. The best thing to do is to just try and adhere to the rules and not try and slip anything past security. The concerns of the airport are valid and delays are more often caused by passengers than overzealous security agents. If you take the time to make sure your cabin luggage is the appropriate size and only contains the appropriate items, you will be a part of the solution and not a part of the delay.
You need to make sure you know the rules of air travel, and make sure you’ve checked to see if they have been updated. Keeping up to date on the regulations will make traveling easier, because the excuse of “oh I didn’t know” will not fly and you will become a part of the delay. International flights can be even trickier as you need to make sure you check the laws of each country that your plan will be landing in that requires you to change planes. For example, international flights usually have a 100ml liquid restriction.
One other tip, when you purchase a ticket, you can pay a little extra to store your carry-on with the regular luggage. The advantage of this is that if your bag does end up being a little bit too big, you can have them store it underneath, as opposed to being fined and overcharged for it when they force you to put it beneath the plane. The nice thing is, because of the crackdown on flight regulations, most airports will have a sample stand near the check in counters so you can test whether or not your bag will fit and meet the cabin luggage size requirements. Make sure you buy a quality piece of baggage; something that falls out of the cabin and breaks into pieces is not going to be worth it. Samsonite cabin luggage is some of the best constructed around and for a good price too.
Consider your fellow passengers when you travel. Try to follow the rules and be ready to be flexible. Security guards at the airport have a stressful job and anything you can do to make the trip go smoothly will greatly benefit you and the other passengers. Adhering to the rules for cabin luggage is a simple way to get to your travel destination without any issues or problems.
