I think the point Harry was making is that Czech airlines are not being regulated to the same standard as U.K. airlines.
The quote below is directly lifted from the CAA website:
Within Europe much of the safety regulations are set by a European Commission body called the European Aviation Safety Agency. This means there is a common set of requirements across Europe on areas like pilot licensing and aircraft type approvals. National regulators, such as the UK CAA, then use those requirements to regulate civil aviation in their country.
As you have repeatedly insisted that "Czech airlines are not being regulated to the same standard as U.K. airlines", could you please elaborate on how that this could possibly be the case? The whole idea of the intra-EU open skies policy is that you have harmonization of the regulatory framework.
And with regard to crappy Eastern European regulation, I assume you also call for Wizzair, Czech Air etc. to be banned from the UK as well?
