American Airlines (AA) uses a complex tiered pricing model for seat selection in 2026. For a standard "Main Cabin" ticket, many seats in the back of the plane are still free to select at the time of booking. However, if you want a "Preferred Seat" (standard legroom but in a better location, such as near the front of the cabin), fees typically range from $4 to $75 per flight segment. For "Main Cabin Extra" (which offers extra legroom, early boarding, and complimentary alcohol), the cost can range from $20 to over $160 depending on the flight length and demand. If you book a "Basic Economy" ticket, you generally have no free seat selection at all; you must pay a fee (starting around $10) if you want to choose a seat before the 24-hour check-in window, otherwise, one will be assigned to you for free at random.
