Thanks for the input. I did reserve a seat for myself but couldnt rotate for the baby on my lap.
Appologies, this is a questiion concerning JAR not CAP really. This was a Private flight but we also operate commercially. The ops manual simply says 7 passengers. No mention of infants etc. Got a boss who likes to keep stating what can or can't be done. These assurances rarely turn out to be correct but they are always made at the last minute. I guess i should get a copy of the JAR's.
The statement of those younger than 3 can sit on a lap seems correct. I^ll go with that till i find what i'm looking for.
