There are two flights from Mumbai to Pune everyday, but it is most convenient to travel by road. The LOC will be able to arrange taxis. The cost of a full taxi each way will be about $50 and the time is about 3.5 hours. Those arriving late at night may want to stay over at a hotel near the airport and travel the next morning.
There are several flights a day between Delhi and Pune and the travel time is around 2 hours.
We would like to point out that there may be fog related delays in Delhi during winter months.
There are Lufthansa flights between Pune and Frankfurt. However, these do not operate on all days and also, have limited number of seats.
There is also an Air India Express flight between Dubai and Pune three times a week.
Further information will be provided in due course.
