The food is outright terrible though subject to route and direction. Flights bound for APAC usually have an offering to accommodate Asian passengers (Singapore chicken+Noodles often which are nice) so you're okay for the C main course. The breakfast is a joke, a few leaves of salad with inedible additions. Flights FROM the United States TO Europe tend to have better C food because they receive US catering instead of Scandinavian.

Alcohol and drink offering is well within expectations and won't leave you disappointed.

In-flight wifi on long haul is excellent and exceeds most competition (if they have it).

The IFE quality in the new cabin is great though the offering is worthless, expect 10 movies and a handful of shows you've already seen. Bring your own content. The old IFE is a joke. Another annoyance with the old IFE is that they turn it on very late in the flight and off very long before landing, generally spending about 10-15% of the flight without IFE. In the new cabin IFE works before take-off and only stops a few minutes before landing.

Service and attitude is a huge hit or miss depending on crew. If the average age of the crew is closer to a 100 than to 0 you're in for a rough ride. Do not expect service, attentiveness or assistance when very obvious things such as broken chairs need fixing. With the older crews also expect constant interruptions and noise from the crew on night flights so bring sleeping aids. About 90% of my long haul crew experience with SK is bad, there are however also outstanding crews, just to few of them. (Ironically I had a JT flight operated for SK yesterday which had by far the friendliest, most service minded and attractive crew I've ever had on a flight with a SK number.)

They market their punctuality very highly and this is often the case, if you travel a lot for business that is a welcoming feature.

Frequent flyer program and lounges are sub-par, we've seen recent improvements on some hubs but there is a long way to go.
