Obviously, this service is not available in any domestic MLL departure lounge, offering shower service. The only showers that I have taken in a departure lounge, are those in the LH lounges in Frankfurt - which do not offer the ironing/dry cleaning service.

However, I ask the question, as an analogy to this service (whether one calls it a dry cleaning service, as the lounges do, or an ironing service) offered by the AC arrival lounge at LHR, and the (formerly AC) YVR airport authority arrivals lounge in Vancouver. If one wants, after an overnight flight, some attention to the clothes one is wearing, this service or lack of it at the AC/SAS departure lounge, may impact one's decision to go to this lounge, as opposed to the AC arrivals lounge, if both options are feasible for the passenger. For this reason, I believe that the question is perfectly logical/sensible, rather than ludicrous.

PS-My question is whether arrival lounges (of any airline around the world) universally which offer showers also offer ironing/dry cleaning services, while any departure lounges around the world, with shower facilities, uniformly do not offer ironing/drying cleaning services?
