I agree with you on this. Why bother renaming it. What a waste of money and time. I admit in some cases it works. The one that springs to mind straight away is John Lennon Airport. However, who can come up with someone so infamous from Wales? I'm Welsh and proud of it but....
No one has suggested Max Boyce International or Rhydian (X-Factor runner-up) Airport
Prince of Wales or Prince Charles Airport would be acceptable, and perhaps Owain Glyndwr, but please keep the celebs out of it. It'll end up being a laughing stock otherwise, not to mention a waste of money that could be spent on more important things
