*Would prefer to send expensive table linens to professional cleaning company (usually this is done back at base). Some a/c's I have worked on have actually carried their own travel iron in the cabin.
* Re: Washing up, had this very situation only the other week, catering company had to come and collect washing up and this was done after we had left the a/c as they took so long to arrive. The handling agent very kindly waited with my washing up until catering company arrived to collect it.
* I have found most operators do not allow/or like the washing up to go off to be washed by a catering company due to breakages and the cost factor.
Hope this info helps.
