Aircraft configurations, seats, service, passenger experience, and ticket price differ greatly from airline to airline.
There are five airline categories — Network Carriers, Hybrid Carriers, Low-Cost Carriers (LCCs), Ultra-Low Cost Carriers (ULCCs), and Charter Operators. Technically there is a sixth category — Regional Carriers — however, these airlines generally get categorized under Network Carriers because they operate on behalf of the Network Carriers.
There are 11 major airlines in the United States that operate scheduled passenger service. Learn more about each of the airlines, see flight reviews, get to know their fleets, and learn about their loyalty programs.
