It’s a semi self-explanatory title - what’s been your worst and/or longest journey to your destination before, wether it be because of disruption or something else. The only thing I’ll say is that it has to be in some way aviation related.
Mine happens to be coming back from Poland, getting a train across the border into Germany, only to find that I’d missed my flight back from Berlin SXF. Waited 6 hours for the next one back to London, then had a 3 hour drive home at 2am. It was a 13 hour journey in total.
Couldn’t find anything like this by searching, but sorry if this is in any way a duplicate.
