About Delta Air Lines
Delta Air Lines is consistently ranked among the world's best carriers for reliability and customer satisfaction, and is a founding member of the SkyTeam alliance with one of the most punctual operations of any major US airline. Headquartered in Atlanta, Delta serves 300+ destinations across 50+ countries from eight US hubs — most notably Atlanta Hartsfield-Jackson, the world's busiest airport — alongside New York-JFK, Los Angeles, Boston, Detroit, Minneapolis-St. Paul, Salt Lake City, and Seattle. Its premium Delta One business-class suite and expanded transatlantic joint venture with Air France-KLM give travellers strong connectivity across the North Atlantic, while the SkyMiles loyalty programme and co-branded American Express cards are among the most lucrative in the industry. A large Airbus A220 and A350 order signals continued fleet renewal through the 2030s.

Booking tips for Delta Air Lines
Compare fare classes carefully
Delta Air Lines offers multiple fare tiers. The cheapest class may restrict changes and exclude checked baggage — compare the all-in price before purchasing.
Book long-haul 3–6 months out
Long-haul Economy sale fares sell fast. Set a price alert and move quickly when deals appear — the best fares are typically 3–6 months before departure.
Use miles for upgrades
Delta Air Lines's frequent flyer programme offers excellent value for upgrades. Earn miles on Economy fares and redeem them for a premium cabin on long-haul routes.
Route via ATL
Connecting via Delta Air Lines's hub at ATL can open up cheaper itineraries — especially when direct fares from your home airport are expensive or unavailable.
