On a flt to Hyd, I would definitely recommend connecting in Europe over connecting in BOM or DEL. DEL is going through fog problems and cascading ATC delays. BOM seems to be effected by traffic overload and challenges of airport revamp as well. All my flts through BOM and DEL have been delayed the past few months. The recommended MCT (Min Connect Time) in BOM and DEL these days is 3 hrs for intnl to domestic transfers.

AMS, FRA, LHR are far better choices to connect for airports in India. Immigration/Customs in Hyd while a little crazy is still not bad. With the new airport, post April 2008, I definitely recommend flying directly to HYD, BLR rather than connect in BOM/DEL.
