It&#x27;s a large airport and when transiting to other parts of Europe, I&#x27;ve found it more painful than smaller airports.  When I&#x27;ve had to go through customs there (US national) the lines have been incredibly slow and tedious.<p>In terms of time&#x2F;distance, some hops at Frankfurt are just as bad or worse than Heathrow (US -&gt; FRA -&gt; Tel Aviv being a really really nice <i>not</i> walk).<p>Given a choice, I prefer Zurich or Munich first, Frankfurt second, and surprisingly my experience with CDG hasn&#x27;t been bad compared to horror stories I have heard.
