Cork weather
Can't imagine WIZZ having to divert nearly every flight ! Amazing that the based Ryanair aircraft hasn't diverted once since 24th November last. The trick when holding at Cork is to patient as the RVR does fluctuate and rarely stays below CAT 2 limits for very long.
Aircraft which bring enough fuel to hold generally though not always get in.
Airlines which send aircraft and crews to Cork that are not CAT 2 compliant are only storing up trouble for themselves.
