My gf flew to Islamabad yesterday. ba.com says that the flight (BA129) arrived at 0601, when in fact it arrived at 0701. Not because it was an hour late, but because Pakistan are currently 5 hours ahead, not 4 (they've
extended daylight savings time for a few months to save electricity). Not just last night's flight either -- searching for LHR-ISB for the next week (at least) says it's an ~8 hour flight that lands ~12 hours after take-off... which is +4.
I've contacted customer services by email, mainly because I (and my gf) would like to know what's going to happen to her return flight. Specifically we're interested in which of the departure and arrival times are correct, since they can't both be!
