Both Airports, Bangalore and Hyderabad, though are far away from the city, but both looks elegant and truly par with other international airports. I stay in Bangalore but happen to work in Hyderabad for some time and was regular flyer between both sectors, which make me eager to write on which is better.Hyderabad, Shamshabad Airport is a clear winner.
Bangalore Airport may look good , but the way Hyderabad Airport layout and architecture is done is simply fabulous. Only good point about Bangalore Airport is that there is only one entry and exit points, I mean not the departure/arrival gates but the main Entrance. In Hyderabad, it sometimes becomes a bit messy near the entrance when it is over crowded, but yet manageable.
Regarding Food and Shops, again in here Hyderabad is far more superior than Bangalore, First time I have seen a Prayer room (for Namaaz), smoking zone and a bar inside Indian Airport, must say very bold move...... Hope that all other airports follow the same trend.
Regarding transport, though both are equally good, even though hyderabad busses are not Volvo, but good thing is that it is non stop A/C bus and from strategic locations, every hour. So no problems with timings you know that busses go evry hour from prominent locations, Bangalore Vayu Vajra VOLVO, though goes faster and other advantage (or rather some may say disadvantage) is that it stops on many places. Only problem with Vayu Vajra is that it is tough to get the bus timings, and we end up booking a CAB.
