We know from this forum that not all aircraft carry the same equipment as others. For example U2's A319s don't have the same HF radios as their A320s, or other airlines A319s.
In this case it meant that they had a higher proportion of cancellations (during the French ATC strike) to Spain, Portugal and North Africa as they could not use Oceonic air space to fly around France.
Not unsafe, by any means, but perhaps short sighted by the bean counters.
It does reinforce the idea that each airline, and their airplanes, have differing rules, procedures and equipment. Winds do change in direction and intesity, as does fog, sometimes in minutes. Just because the 'blue' airplane, or the 'white' one operated doesn't mean other coloured airplanes are going to do so.
If you are unhappy with the situation, you have a choice.

Reason: Wind and fog
