Yes, you generally earn significantly more miles when flying First Class compared to Economy, though the exact "bonus" structure has shifted in 2026. Many major airlines, including United and Air Canada, have moved toward revenue-based earning models where you earn a specific number of miles per dollar spent on the base fare. Since First Class tickets are substantially more expensive, your total mileage accrual is naturally higher. Furthermore, legacy carriers often provide a cabin bonus multiplier, frequently granting an additional 50% to 150% bonus on top of the base miles for premium cabin travel. Elite status members also receive further multipliers, sometimes earning up to 11x or 6x miles per dollar spent. While "Basic Economy" tickets in 2026 often earn zero miles or a very low percentage, a First Class seat ensures you are earning at the highest possible rate, helping you reach your next reward flight or status tier much faster than those in the back of the plane.
