Business class is actually Economy
I sent this email to Korean Air after an awful 'business class' flight from Seoul-Singapore:-
"While flying on the above flight in Prestige Class there was no extensive selection of wine as purported on your website, nor did the food remotely resemble how it is presented on the website: a selection of gourmet food with a range of options served on and in real crockery with the full beverage service. You may well suggest, as the cabin crew did that this is solely down to the current Coronavirus (Covid-19) regime affecting airlines. However, numerous online travel reviews conducted through the period of coronavirus including the large wave of domestic infections in Korea (August 2020) show that other flights running at this time have provided a service comparable to the one advertised. With this mind, it is clear that the reduction in service provided on KE645 was a cost-cutting measure and had nothing to do with the pandemic. For the catering service, everything was boxed or served in plastic. I was presented with two options for dining: "beef or seafood" and "red or white wine". When asking for a gin and tonic, I was told the "cocktail service had been withdrawn". I would like your detailed comments on this and ask if this is standard service on this flight.
On a separate note, I make it clear that had I known the service in Prestige Class was comparable to economy I would have opted for economy or with an entirely different airline, bearing in mind Singapore Airlines was offering a comparable fare for the same dates. To offer a service so distinctly different from that advertised is both misrepresentative and disingenuous. The current climate is an opportunity for airlines, such as Korean to prove particularly with their premium products that yours is an airline worth returning to when business resumes as usual. You will see from my email that this is not the case; it would seem that Hanjin is encouraging passengers to fly economy, or most likely with other carriers."
Korean Air keep claiming that they would not offer business class at this time due to Covid-19 but this cannot be the case as they are offering the full service on other legs. Furthermore, it can also be deducted, through reading blogs and analysing airline reviews on YouTube, that Korean Air have at times been providing the full service, but this is besides the point, as at the time of booking they were advertising a full service in Prestige class, with no disclaimer regarding Covid-19. It seems Korean Air are interested at cutting costs in business class at the expense of full fare paying passengers and using other excuses as a guise for their incompetance.
