Regularly the food supplied by [Airline] is not sufficient for the length of duty. For example, my last duty started at 0500 UTC and finished at 1430 UTC, representing 9.5 hours of duty time. The food supplied for that duty per pilot were:
1 x Oat Burst porridge pot
1 x Croissant or Pain au chocolate
1 x penguin chocolate bar
1.5 x apples
Plus 1 extra pack of 3 biscuits to share.
This effectively needs to cover a breakfast and lunch period and is insufficient calories for the length of time.
The crew food is loaded in the morning, it often gets consumed through the day, because each crew does not have enough. Therefore, by the evening flights there is often no food at all. Our alternate procedure is to have passenger food which also runs out through the day. For my last five late shifts I was provided with nothing more substantial than a KitKat and some Pringles.
