What's the difference between coach and first class?
The biggest difference between coach seats and first
Amenities may include bigger, more comfortable, and spacious seating. The food and drinks served are of higher quality, better service, and supplied continuously from takeoff to landing. Many airlines give first class customers additional personal items such as several toiletries, sleeping masks, robes, slippers, and other comfort items. The entertainment and electronic selections offered are more ample as well.
If you require the additional space or simply enjoy being pampered then first class is the only way to go. For those that would rather save money and consider a flight a good opportunity to catch up on some sleep then consider a coach ticket.
