So then we should be worried to land in Nice aswell or Gatwick? How about Madrid Barajas?
NCE has a giant flashing X when the usual landing runway is closed.
LGW swap the lighting system over and have a different approach type when the usual landing runway is closed.
MAD you prepare for one of the four options, and whilst they sometimes spring a different one on you there's a precision approach to all of them.
PSA is a chaotic place at the best of times. The NOTAM was terribly worded and started with the words 'RUNWAY 04R/22L AVBL...' with the word CLOSED not mentioned at all. There is no ATIS, only weather passed by approach in heavily accented English faster than you can write.
Only the tapes will prove which runway they were cleared to land on. I would not be the least bit surprised if the controller issued the clearance for the closed runway.
