d3 is such a gamble to fly these days. Last time I flew D3 was in …2005. IIRC, December 2005. That morning, we were trying to get back from LHR-JFK. As we made our way to the airport, we get news of a fuel explosion near the airport, in Hemel Hempstead. Our AAunt bid us good luck and told us to try and attempt a flight from Paris or other cities.
Jetnet was showing all red, no flight availability. We took a chance and nailed 2 F class seats home on the 777. Amazing.
Nowadays, I would not take a chance unless I was single.
