Several private air-lines had come and gone East-west, Modi,Gujarat air ways etc etc...where are they now...? Now many are coming again....Do theyhave good infrastructre to fly..? There are some small air ports which donot allow night-halt,night-landing,night fly etc..Example Pune air port. Why these air lines cover only Metros Delhi etc.... Consolidation of air-lines should come. Like we talk about Banks consolidation, merger etc etc. Passenger should not be tased with costly fares... We have to wati and watch.......Privatisation...a good air-lift....
