Hi… I tend to agree with VK on this one; the extra £40 for upgrade to Club is worth it. BA and LX are the only airlines to offer this to my knowledge so I tend to use both when schedule permits and price is available of course
While Mark R is correct that other airlines offer lounge hot items as well, I have stopped using KLM due to the 3-3 Europe Select config and food is not presented very well. Staff is always good, but KLM does not stack up to any other European carrier in the front cabin. In economy it may be ok.
When I travel on holiday in Europe, I like the relaxed atmosphere business cabin and therefore spend the extra surcharge on BA and LX.
