I know what you mean. The definition of a UK company is very vague but in simple terms I am thinking of companies that have staff based in the UK, living in the UK paying income tax in the UK and occasionally paying a little corporation tax to HMG. Obviously, Jet 2 is the closest but others fit the bill more closely than Aer Lingus or Aer Lingus UK which would be operating on a big loan from a foreign company. I suspect that far from offering competition on the Atlantic, this is just Willie Walsh's final attempt to kick Sir RB in the nuts before retirement. If so, the only losers will be UK workers.
