2024 was a wild ride for U. S. airlines. Just five days into the year, a door panel fell off a Boeing 737 Max operated by Alaska Airlines, causing delays and raising safety concerns. Two weeks later, a federal judge blocked JetBlue's plan to buy Spirit Airlines, leaving Spirit to face its own challenges. Among these was a tech meltdown at Delta that caused hundreds of flight cancellations and left many travelers stranded. Situations like these pushed Spirit to file for bankruptcy in November.

Meanwhile, Delta and United, the top two profitable airlines, focused on premium services. Delta opened new lounges for high-paying customers, while United expanded its network with more premium destinations and announced free Wi-Fi via SpaceX's Starlink. Southwest Airlines made headlines by announcing they would start assigning seats, aiming to increase revenue.

American Airlines faced internal issues, while smaller airlines like Spirit scrambled to adapt to post-pandemic costs and competition. JetBlue focused on cost-cutting and profitability. Alaska Airlines continued its merger with Hawaiian Airlines and planned global expansions. Frontier moved towards upscale services with plans for domestic first-class seats and bundled offers. Allegiant faced challenges with its hotel business but showed high demand in its airline services. Sun Country saw improved performance and updated guidance.
