KLM are showing their Promo "Light" fare from Dublin to New York JFK on 26 April and return on 6 May as including 23kg of checked in luggage (see screenshot). After selecting both flights, on the next page the website shows, there are two different places you can click that confirm this. But then when you check out, you have no checked baggage. I called the phone line and the woman said because on the payment page, after the above one, there is something you can click to check flight details, and on the bottom of the box that opens up there is "baggage" that you can click and then it doesn't show the baggage. She claimed this made it OK! The only thing she could offer me was a refund to my credit card, that will take 72+ hours, meanwhile I can't rebook as there is not enough capacity left on my credit card. I told her this violates UK advertising law, as it is false advertising, but she could still only offer me the refund. She also only told me it would take 72+ hours to return the money after she had processed the refund. As I have had good experiences with KLM in the past, I am going to assume that this is a case of them not owning their mistakes and honouring their promises, rather than trying to deceive customers, but it is certainly making me reconsider flying with them in future. Whether what they did is illegal or just bad practice, it doesn't give you confidence in them. This also applies to Air France as they have the identical website with the same offers, so are presumably the same company. Although I can't speak to their customer service line, which I would imagine would be the same but it is possible it is not.
