On the flip side, ignorance can be bliss some times.
I was due to fly LCY - FRA on LH in the evening and was tracking the assigned aircraft to see if it was running behind throughout the day.
Saw on FR24 that on the flight XXX - FRA, which would position it ready for FRA - LCY, the aircraft had instead diverted to MUC.
Of course I was straight on the phone to LH seeing if I could get rebooked onto an LHR - FRA flight around the same time as I was originally scheduled.
Agent was ¯\_(ツ)_/¯ as "your flight is neither cancelled nor delayed" which I argued was hard to believe given the diversion and lack of spare E190/E195s.
Did a HUCA but similar result. Pushed them enough this time that a supervisor was consulted and was advised "an aircraft will reposition to operate your flight". ... but whatever...
I headed to LCY and could see on FR24 the aircraft leave MUC and head straight to LCY. They flew it empty so it turned like a champ and we left with only a small delay.
And that was the day I learned that being an ignorant traveller rather than an avgeek can sometimes save you some stress... 🙈
