Not sure if this is accurate or not but on another thread they were commenting on the cost of the specialist grit / de-ice compund at around £30,000 a day to clear a fully snowbound runway with the grit osting upwards of £5,000 a ton.
Even if the figures aren't accurate it's stilla few quid either way (excluding kit and labour) so no doubt they took one look at the arrivals board and thought, bugger it let them go elsewhere.....
Dire state of affairs.
