Use Lounges
People who are frequent fliers should take advantage of the lounges at the airport. Some people use their American Express Platinum card for this. Some airports around North America you can enter the lounges for free just for being a cardholder. However, some lounges might charge a fee, but it’s worth it at the end of the day.
