This will lead to a shortage of helicopter pilots for the North Sea.
Many helicopter students come to the USA, become Heli CFI's and then go home with 1,000 hours. North Sea operators will have to 1) lower their standards to 200-300 hours 2) hire more military pilolts if they can find them 3) allow USA pilots to emigrate to the EU
I don't think this will affect airlines as they may be will to take on 300 hour pilots.
