Hmmm... wonder why I wanted to revive this thread....
Anyway, just posting this question from the logos thread to reach a wider audience..
I'm watching BA A319 G-EUPX flying over the Czech Republic with an ID of ISC3534. ISC is an old code not apparently in use - anyone got any ideas what that's about?
EDIT it's just landed at Ferihegy LHBP - arrivals board there does show BA870 arriving about now, but why is it using that ISC code?
