I flew using economy comfort to Chicago. These seats were ok. Not amazing since it cost me an extra £84 to book the seat but it was ok. The plane was an older plane so inflight services was a bit dated. Small video screens, etc. My return was awful. I paid £48 for more leg room as nothing was available in economy comfort or business class. The seat was tiny!luckily I'm not a big person. I was next to the toilets, so busy.. And poor inflight entertainment. Probably the worst long haul flight I've had.. Who can sleep in such cramped conditions? KLM you need to get rid of these older planes. Are we animals?
