About 2 years ago, I was flying from Singapore to Cairns, Australia in Business (a 767-300 red-eye) and accepted a glass of champagne and made a comment that it was my birthday and wanted to celebrate in style. The F/A made a comment about promising me a beautiful sunrise. I was shocked when about 20 mins prior to landing, I was invited in the cockpit to witness the sunrise. I stayed for the landing. I went from extremely tired (after only sleeping 1 hour) to exhilarated.
It was a truely special birthday I will never forget!
