On the TTN to FLL route in January, low-cost carriers such as Spirit Airlines frequently offer the most competitive nonstop fares but charge extra for carry-on and checked bags, seat selection and other add-ons. Legacy carriers (American, Delta, United) typically route passengers via their hub cities and include more generous change/cancel policies, lounge access options for premium passengers, and wider schedule coverage, which can be useful during winter disruptions. When comparing airlines, evaluate total trip cost including baggage fees, seat preferences, schedule convenience, and frequent flyer benefits.
