Being Rude Gets You Nowhere
Being painful leads nowhere in life. Besides, it certainly doesn’t help in flight. Even if an upgrade is available, flight attendants won’t give it to you. You already knew that, though. You probably didn’t know the next part.
If you are a frequent traveller, it will be noted on your account that you are annoying and unpleasant. Just like getting a bad mark at school, you will be considered a bad traveller no matter how many flights you book! Do you want an A in flight or an F? If you want to get an A, be polite and you’ll get the crew’s favours on board every time, and each of your trips could be a comfortable one. Then, remember that these are basic human manners to be polite to others?
