First class is where airlines try to give their passengers the best in service, seating and amenities. First class seating usually consists of extra wide seats made from the best leather or materials, lots of leg room, top quality gourmet food, excellent wines and liquors and plenty of service for passengers that require assistance or just want to enjoy a flight.
First class is usually two to three times the amount of a standard airline fare, but for many people that either fly for business or are on a special once in a lifetime trip is well worth the monetary value for the level of service that they receive.
Everything in first class is done to satisfy the passenger. You can enjoy a gourmet meal developed by a leading chef and eat it with real silverware and dinnerware. You also have a choice of fine wines and top shelf liquors.
Comfort is taken to a new level, with some first class seats being able to fully recline, like a bed for extra long trips. There is usually plenty of entertainment available such as satellite TV, music and magazines. Service is usually at a much higher ratio than economy or even business class. If you have the resources or are on a once in a lifetime trip, it definitely pays to fly first class.
