it's still a building site that the traveling public have to endure each time they travel through it
Rubbish, there has been no building work to the terminal or the CTA for the last 10 years which is in part why Luton has come bottom in the airport vote
You will have to give a couple of examples of what has taken place that the traveling pubic has had to endure and not make sweeping statements. I can't think of anything apart from tinkering and then that was only shifting the drop off area away from the terminal to comply with the DoT and the exit route which were both minor and were completed in a matter of weeks. Oh and a few retail outlets that have changed hands over the years but that happens at all airports.
With respect, continual improvement that has led to no improvement is not progress
You need to look at the first post here
