In 8 days. I am fully aware of that but I must honestly say I expect a notification when my trip is not only slightly changed to accomodate for a small schedule change but re-issued on another airline and when the metrics are changed that much. It is not the usual 7.46737883949 minutes outbound change, it is SIX hours earlier (meaning getting up a 2am) on one trip directing and plus EIGHT on the return.
OK, yes, that's unacceptable (but, sadly, not unsurprising).
