FROm the NWA crew
There is no requirement to have a french speaking FA on YUL flights. I have done this flight many times without a French speaker and never had a problem. You MAY come across a French speaking FA just by coincidence. (small chance). For the record there are interpreters on Pacific flights only. Again in my experiences, I never had problem with language.
Pillows and Blankets are avialable on RED_EYE flights in all cabins. On the flight from SFO-DTW you will get a predeparture drink, inflight drink with spinzles & nut mix. We also have bananas and granola bars to offer before landing. Its been my experience 99% of the time that everyone falls alseep before we even get airborne. I don't wake people up to offer granola bars/bananas/drinks before landing. If anyone is awake, I'll quietly offer them.
