As discussed in the thread about Rosh Hashana cards in September they weren't letting liquids through security. They didn't appear to be searching for liquids this time. Also they seemed to be more lenient on the internal flight from DEL to BOM than they have been in the past. I think that they've chilled a bit with regards to the liquids and electronics. I found it very odd that LY issued the big warning to travel agents about BOM considering my experience there in November and now. Seems like they were just a bit slow on the uptake. Of course YMMV so perhaps others will chime in with their experiences of late.
