Thank you Wisi1965, appreciate your comments. I am not expecting a refund but it was a thought to try, as the money paid out for the tickets was a lot for premium service. To which I asked for credit miles instead and it has been silence from Swiss. Actually a phone call would have made a big difference and put things in order.
I am now a convert to EK having flown them on to Hong Kong and as well to Paris last month – “wow” what an airline.
