The standard allowance for baggage check-in for intra-Europe flights (including flights TLV - Europe) is 20K per person in coach, 30K for C class. This is for total weight, with a limit on 2 pieces as well. BA allows a little more in weight (23, 35 as I believe).
The standard for flight to/from the US is 2 pieces, up to 32K each. BF pax get a 3rd piece for free as well. (total of 64K for coach, 96 for BF).

This is a very good point raised by craz.
