I do not dispute that cee cee. But if only SQ had asked me? If only their automated system had recognised passport validity dates? If they had not asked but had put it in the Ts&Cs - then they could have smugly pointed this out to me.
But they did none of those and only referred to the requirements of the destination country. Accordingly, I felt they were in error and gave me undue anxiety. Not something I associate with SQ. From the first booking to travel was about four months and I would have renewed my passport - if they has stated their requirement.
