Delta Air Lines, KLM, Air France, and Virgin Atlantic are all part of the SkyTeam alliance and have partnerships with each other for smoother international travel. While they are not direct subsidiaries of one another, they collaborate to offer joint services, including code-sharing, coordinated flight schedules, and shared airport lounges. This means travelers can book flights across these airlines with ease, benefiting from greater connectivity and convenience, especially for long-haul travel.

When it comes to India, these airlines operate flights to and from various major cities like Delhi, Mumbai, and Bangalore, among others, offering multiple options for travelers flying between India and Europe, the United States, and beyond. Delta, KLM, and Air France operate extensive networks to and from India, while Virgin Atlantic typically focuses on connecting India to the United Kingdom.

Here’s a summary of how these airlines connect India:

1. Delta Air Lines

• Delta offers non-stop flights between major Indian cities and its hubs in the United States, such as New York (JFK), Atlanta (ATL), and Detroit (DTW).
• While Delta doesn’t operate direct flights to India from every U.S. city, its partnership with KLM and Air France enables more routes via Europe.

2. KLM Royal Dutch Airlines

• KLM operates direct flights from Amsterdam (AMS) to major cities in India, including Delhi, Mumbai, and Bangalore.
• KLM is a key player in connecting Europe to India, with convenient connections to Delta's network in the United States.

3. Air France

• Air France offers direct flights from Paris (CDG) to several cities in India, including Delhi, Mumbai, and Bangalore.
• As part of the SkyTeam alliance, Air France works closely with Delta and KLM to provide a seamless travel experience across continents.

4. Virgin Atlantic

• Virgin Atlantic operates flights from London Heathrow (LHR) to several cities in India, including Delhi, Mumbai, and other major hubs.
• Although Virgin Atlantic is not part of the SkyTeam alliance, it has strong ties with Delta Air Lines, and together they offer shared services and codeshare agreements to improve connectivity for Indian travelers heading to the U.S. and Europe.

Code-sharing and Alliances

• Through SkyTeam (for KLM, Air France, and Delta), travelers can enjoy reciprocal benefits such as shared frequent flyer miles, the ability to check in with any of these airlines, and use of partner lounges across the globe.
• Virgin Atlantic and Delta share a deep partnership outside of the SkyTeam alliance, meaning passengers can enjoy a similar experience with joint flights and shared perks between the U.K. and the U.S., as well as to India.
