How Much Does It Cost To Upgrade To Business Class At Check-In?

How much does it cost to upgrade to business class at the airport? This article will answer the question in more generalized terms. While airlines clearly list their business class fares online and state their upgrade process with points, they don’t advertise the rates at airports. Today, airlines want passengers to upgrade online before getting to the airport, and it’s not in their interest to encourage business class passengers to wait until they get to the airport.
