There are a few important restrictions concerning the people who can fly via air bubbles and Vande Bharat Mission flights. To understand more about the same, check out the points mentioned below.
1. If you are taking a VBM flight, your choices would be restricted to a handful of airlines that are affiliated with the government of India. Air India and Air India Express are the two airlines that are the frontrunners of VBM flights. You need to be eligible and approved to fly from the VBM flights though.
2. When it comes to air bubble flights, you are spoilt for choices. As long as you are travelling to and from one of the 18 countries with which India has formed bilateral arrangements, you can pick from a slew of airlines that are currently functioning on the said route and have been allowed by the government. There are no restrictions on foreign passport holders, and they are allowed to fly with a valid visa.
3. Although depending on your passport and country of origin, you are only allowed to travel from the airline of the said country, a few amendments in the rules have been made. This means that you would be allowed to travel from British Airways or Lufthansa from the United States to reach India, if the flights connecting are from London or Germany. It primarily depends on the connecting hubs and the route the flight is taking to reach India.
4. Restrictions for flights flying out of India would disallow Indian passport holders to fly from Lufthansa or Virgin Atlantic on connecting flights beyond the UK or EU. This is despite you bringing a legitimate ticket holder. Hence, you must read up more on the airline regulations and restrictions before booking your flight tickets.
5. The rule of connecting flights does not apply to foreign nationals. They would be allowed to travel beyond the airline hubs of connecting flights. For example, a foreign national can travel beyond the UK or the EU on a Lufthansa or Virgin Atlantic.
6. The idea of such complicated rules is to ensure that the travellers only choose to fly the "home" airline at the end of the bubble. In simpler words, the home destination should be travelled in the national or "home" airline to avoid international concerns. For example, for a traveller travelling from the United States to India should either travel by United or Air India and not a third airline belonging to a different country.
