No offense to radonc1, but who exactly is going to catch you? It's not like they scan a bar code to verify you are on a manifest of a flight. They just glance at the date, to/from and the name.

Now if you tried that in Mumbai, that's a different story. I'm sure other airports do this, too, but I was recently flying out of Mumbai and they have the manifest printout at the airport entrance and if you are not on it you can't even get into the building. They match up your passport with the flight manifest and then they let you inside.
