  • If you’re in a hurry and need to get to Boston Logan Airport (BOS) as quickly as possible, take a taxi instead of using public transport. Not only are they easily accessible from anywhere in Boston, but they also take a very short time from downtown Boston to the Airport Terminal.
  • Boston Logan International Airport is a major hub for Delta Air Lines. Therefore, you should consider booking your flight with them since they will have more flight options compared to other airlines.
  • To get wheelchair services at Netaji Subhash Chandra Bose International Airport (CCU), ensure that you inform your travel agent or airline that you will require the services at least 48h before departure. This gives them enough time to organize with the officials on the ground and make the necessary arrangements.
  • When booking connecting flights, go for the automatic transfer instead of the self-transfer option. This will save you the trouble of having to check yourself and your bags into every individual flight.
