Extra Bags Do Not Really Make A Huge Impact
Each passenger is allowed to have at least one stowed luggage during the flight. However, this means that they will have to pay some fees if they want to bring more baggage. Although planes are typically designed to accommodate just a bag per passenger, extra bags would not really change anything. Planes have been designed to have the right center of gravity to takeoff without a problem. Depending on the number of checked bags on the plane, airlines normally use sandbags to balance out the weight. This does not exactly explain why they charge you a lot of extra bags, however.
How To Improve Your Chances Of Getting An Upgrade
It should be a given for everyone to treat others with respect no matter what, but it often pays to treat your flight attendant very well. According to flight attendants, they like customers who smile at them and respond with “thank you”. Apparently, this does not happen all that much on flights! Aside from basic courtesy and etiquette, it might be possible for them to give you an upgrade if there are any availabilities. If this is what you are looking for, keep in mind that they will be more willing to do so if you are pregnant, too tall, or a frequent flyer.
