Bidline is in many companies - virtually every company in the USA has a bidline system - many limited to 75 block hours per month at that, in comparison to our 86/88 hours.
Allowances - ground staff on duty probably get more than flight crew since our changes. £2.50 per hour (taxed at 18%) does not go far in many destinations (OSL, ZRH etc in SH, HKG etc in LH).
Differences still exist with the captain being paid more than ....? Tell us exactly what you mean, cos' I think you'll find that you are wrong, all flight crew get £2.50 per hour TAFB (reduced proportionally if we get back early!).
TAS - I presume you mean Time Assignable. Usually the company's doing not the pilots'. Correct me if I'm wrong, but TAS results from the company canceling a flight or changing the type. Then the pilot is made time assignable, giving the company the opportunity to reuse them - extra standby in effect. If they then choose not to use him, then it's hardly the fault of the pilot.
Draft Payments - paid overtime in efffect for working over and above contracted hours. When required (not that often) it is often because of c*ck ups in other departments. The actual amounts paid are not much different to those at LGW under the Carmen rostering system for Rest Day working. Another thread at the moment suggests that Ryanair pilots are paid Eur 150-ish per block hour overtime - that is more than I get for overtime.
