Ryanair use steps for the same reason - except they do it all the time, whatever the weather conditions.
However, airbridges are used whenever the weather is poor or deemed a better option (ie large number of PRM passengers).
Ryanair don't use airbridges unless forced to do so as it costs money to use them.
Using airbridges is just as quick at boarding via steps only, especially as not all the passengers are at the gate when boarding starts. Jet2 uses them all the time at GLA unless they are at a stand that does not have them or are at Gate 30.
