Historically and fundamentally, the three primary types of seats or "classes" on a flight are Economy (Coach), Business, and First Class. Economy is the most basic and affordable tier, featuring standard seat widths and limited amenities, though it is often split into "Regular" and "Premium" versions in modern fleets. Business Class is designed for higher comfort and productivity, typically offering wider seats that may recline into "lie-flat" beds, enhanced dining, and priority airport services. First Class represents the pinnacle of luxury, often featuring private suites, gourmet chef-prepared meals, and personalized concierge service. While many airlines are now merging First and Business into "Super-Business" categories, these three remain the standard pillars of aviation seating. Beyond class, seats are also categorized by their position: Aisle (for easy access), Window (for views and sleep), and Middle (the standard "squeezed" seat, often featuring more power outlets in modern configurations).
