My last experience using the Frankfurt airport was terrible. I had no idea how long the lines would be and how many security and passport checks were required. Remembering this, I took an early train from Freiburg to get to Frankfurt airport at 8:10--over 2.5 hours before my flight left. (!)
I was ready for all the inconveniences I had in October, but there were none. It was an easy walk through one security point and to my gate. No passports. Nothing extra. It was like flying within the US. Actually, better. I’m currently lounging in a Leisure Zone with a free copy of the International Edition of the NY Times.
Errol explained the difference: I was flying to Glasgow in October and Rome today. Although the UK is still in the EU, they’re out of the Schengen. Italy is within the Schengen. The Schengen is an area in the EU where passport checks and other types of border control have been abolished.
I feel like UK residents should have experienced the delight of travel within the Schengen before the Brexit vote.
