Charles-P, I can understand your comments about Schiphol lacking warmth, I think it is the focus on functionality and maybe the Dutch way of life. I guess that as I have become accustomed to Schiphol I quite like it. I live north of Birmingham and for me it is far easier to fly BHX to AMS to connect than travel to LHR. I did use to drive to LHR but got caught too many times in traffic hold ups and blocked M40 that I wanted a change. Train to LHR was just too much hassle so BHX to Amsterdam (or Paris) became my preferred choice.
If you get the chance to fly on one of KLM´s revamped 747s I can recommend seat 1A or 4A for peace and quiet.
