American Airlines vs. Delta: Which Is the Best Airline in 2025?

When choosing between Delta Air Lines and American Airlines for your next trip, it’s important to look beyond just ticket prices. Both airlines are major players in the United States 🇺🇸, but they offer different strengths, especially when it comes to reliability, customer experience, and loyalty program benefits. This comparison will help you understand the key differences, so you can make the best choice for your travel needs—whether you’re a frequent flyer, an international traveler, or someone looking for the smoothest journey possible.

Overview of Delta Air Lines and American Airlines

Delta Air Lines is widely recognized as the top major U.S. airline in 2025. It has earned this reputation by consistently delivering strong on-time performance, fewer cancellations, and high customer satisfaction. According to industry rankings, Delta has held the number one spot for seven years in a row, showing its commitment to operational excellence and passenger comfort.

American Airlines, while not leading in reliability, stands out for its loyalty program flexibility and global route coverage. Its AAdvantage loyalty program is considered one of the most generous, especially for travelers who value earning and redeeming points for international flights. American also offers a broad network of destinations, making it a popular choice for those who travel abroad frequently.

Side-by-Side Analysis: Requirements, Timelines, and Costs

To help you decide which airline fits your needs, let’s break down the main areas where Delta Air Lines and American Airlines differ.

Operational Performance and Reliability

• Delta Air Lines: Known for its excellent on-time performance, Delta has fewer flight cancellations and delays than American. In 2025, Delta received a perfect five-star reliability score, which means you’re less likely to face unexpected disruptions when flying with them. Delta’s focus on operational excellence is a key reason why many travelers choose it for important trips or tight schedules.
• American Airlines: While American offers a large network, it has not matched Delta’s reliability in recent years. In 2025, American ranked seventh in overall airline performance, reflecting more frequent delays and cancellations. If you need to arrive on time or have connecting flights, Delta may offer more peace of mind.

Fees, Pricing, and Hidden Costs

• Checked Bags: Both airlines charge $35 for the first checked bag on most domestic economy tickets. However, American increases this fee to $40 if you pay at the airport, while Delta keeps it at $35 regardless of where you pay.
• Seat Selection: Fees for choosing your seat are similar on both airlines, but the exact amount depends on the seat location and your fare class.
• Pet-in-Cabin Fees: Delta charges $95 each way for pets in the cabin, which is lower than American’s $150 fee. However, American recently improved its pet policy, allowing travelers with pets to bring an extra carry-on or personal item.
• Carry-On and Personal Items: Both airlines include a personal item and carry-on bag with most fares. However, restrictions apply for Basic Economy tickets, especially on American, where you may not be allowed a full-size carry-on.

Loyalty Programs and Elite Status

• American Airlines AAdvantage: American’s loyalty program is a major draw for frequent flyers. In 2025, the program kept its status thresholds the same (Gold: 40,000 points; Platinum: 75,000; Platinum Pro: 125,000; Executive Platinum: 200,000). The program is praised for its flexibility, valuable partner award redemptions, and no recent devaluations. This makes it attractive for travelers who want to use their points for international flights or with partner airlines.
• Delta SkyMiles: Delta’s loyalty program is also strong, but recent changes have made it harder to reach elite status. In May 2025, Delta reduced pre-boarding privileges for its top-tier Delta 360 members, making them the same as Diamond Medallion members. While SkyMiles is still a good program, these changes may affect travelers who value elite perks.
• Lounges: Both airlines offer premium lounges. American’s Flagship Lounges are especially good for international premium travelers, while Delta’s Sky Clubs are known for comfort and service.

Customer Experience and In-Flight Services

• Delta Air Lines: Delta is recognized for its friendly staff, free messaging, and expanding Wi-Fi options. Passengers often report a smoother, more enjoyable onboard experience. Delta is also more flexible for Basic Economy travelers, especially when it comes to carry-on allowances.
• American Airlines: American offers in-flight meals, Wi-Fi, and entertainment, but the quality and availability can vary depending on your cabin and route. While American has improved in some areas, Delta still leads in overall customer satisfaction.

Financial Health and Corporate Developments

• Delta Air Lines: In July 2025, Delta reported record revenue of $15.5 billion, a 13% operating margin, and $1.8 billion in pre-tax profit. The airline also announced a 25% dividend increase, showing strong financial health and confidence in its future.
• American Airlines: American has kept its loyalty program stable and continues to make small improvements for frequent flyers. However, it has not matched Delta’s financial or operational performance in 2025.
