British Airways provides complimentary amenities in coach not found on US carriers: A hot meal, snacks, beverages other than water or coffee/tea. Their media selection is superb. They seem to work hard to make a nine-hour flight over The Pond as tolerable as possible.

My comfort was better on the return leg because I had the extra leg room that comes with being seated on the emergency exit row. However, regular coach seating is at best tolerable. You are packed like sardines and the seats are firm, to put it mildly.

una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

This was in coach class, so I understand the cramped quarters, but even on a long haul flight (BA 49, LHR-SEA), how could they justify the seating in the planes? Perhaps BA executives should fly coach class on one of these planes to understand what they are putting their customers up to. Here are 2 additional items that should be a no-brainer to fix: a) They ran out of fresh bottled water. For the last one hour, all they could offer was sparkling water b) Somehow BA seem to be saving on food portions (or their caterer needs to be changed) - lunch/dinner portions are way too small.

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?
