First class is the most luxurious class of accommodation on a train, passenger ship, airplane, or other conveyance. It is usually much more expensive than business class and economy class, and offers the best amenities. The first-class section of a fixed-wing passenger aircraft is typically located in the very front of the aircraft. However, many commercial carriers have completely removed first class altogether from their international flights, only offering business class as their highest level of international service. First class passengers are usually granted access to lounges at airports while they wait for their flights.
