In recent months, we have heard from 2 couples and
several single travelers that European travel agencies are warning to stay
away from Delta (long waiting times at check-in and poor service,
particulaly eastbound over the Atlantic) and Atlanta ( very slow arrival
clearance with baggage that has to be recovered, handled and checked in
again. Long lines in front of uninterested customs people etc.)

Delta is a fairly mediocre airline, but certainly no worse than
European carriers. As for Atlanta, it's a model of efficiency and
good customer service compared to a big European airport (with very
few exceptions like Schiphol).
