PSA more than a question, but on the SFO-TLV flight davening creeps up on you pretty fast. departure time is about 915, by the time meal service is over and they shut the lights it's pretty close to 12am origin time, and the time to daven starts at 2am or so, and zman krias shema isn't that long after. you don't have this on the direct TLV-LAX flights, because they leave at 1 pm, and the ast coast is a whole different story.
in addition shkiah hits when you're somewhere over Europe, or just when people are waking up. My guess is that many people are unaware.
All this is compounded greatly by the fact that on the dreamliner you can't look out the window easily, which is really cool, it is automatically darkened when they want you to sleep, but if you go to the galley or wherever it's bright daylight.
