I was talking to a friend recently and he referred he was in a delayed flight from Brussels a couple of weeks ago due to de-icing.
Basically the plane already had an initial delay to which summed up the need to apply liquid to avoid ice on the wings. The pilot said it hadn't been done properly so they had to have it done a second time, which resulted in another wait of almost an hour.
Is he eligible for compensation or does this fall in the weather conditions situation. It's not very clear, he arrived more than three hours late, and service at the airport was terrible, but in other hand one feels that safety should come first and companies shouldn't have to weight about losing money on compensations vs safety.
