Pros: The crew and staff were all friendly, helpful, and professional. I was surprised that on a 3 hour flight, they served a full meal and even more surprised that it was quite good.
Cons: First, flying to Seoul then onto USA a few days later should be considered international and allowed 2 bags but they only allow one. Not fair to pay a lot more for a 2nd bag.
Second, after boarding and taxiing, the pilot announced that there was a mechanical problem and we would return to the terminal. We all had to get our bags, get off, then get them right back on. All planes have mech problems, but after takeoff I notice things like bathroom lights didn't work. No soap or towels. Speaker system didn't work wel, etcl = general lack of maintenance.
