Jul 22, 2019 at 4:46 comment added mbloch @Daniel see the question linked in my comment above. This is a machloket. In the flight I describe (TLV to LA) one doesn't go back in time on the clock (i.e., time moves forward more slowly without jumping back). It is possible that in very northernly latitudes you leave at 4pm and arrive at 3pm.
Jul 21, 2019 at 22:30 comment added Daniel @mbloch not sure what you mean by not flying back in time. If the sun has set and then it "unsets" isn't that halachicly going back in time?
Jul 21, 2019 at 18:19 comment added mbloch @Daniel this phenomenon with the sun exists indeed and I wrote about it here on MY. I do not believe you fly back in time though but admit it might be possible if flying e.g., from Helsinki to Northern Canada.
Jul 21, 2019 at 16:48 comment added Daniel @mbloch Actually, as far as I know, it is possible to fly "backward in time" due to the great-circle flight path. In particular, flights traveling west over very northerly latitudes may see the sun re-emerge briefly after it had set.
Jul 21, 2019 at 16:45 comment added Daniel The questions were: "Are there particular lifting of fasting restrictions if traveling for a permitted purpose? Are there poskim who would allow eating/drinking lechathila? Does it make a difference if the fast happens on the day after the “real” date because of shabbat?" This doesn't address any of these questions.

Feb 12, 2019 at 21:14 comment added mbloch I did read the four answers. But I do not see how they apply here. If you fly westward, time moves forward, just slower. You never to get arrive somewhere where it is 17 Tamuz where you have a 17 Tamuz behind you. I exclude dateline issues which are not relevant for most Jews. The answers apply when you fly eastward and finish your fast quicker (happened to me once on London-Hong Kong, shorter fast but tough flight with dehydration and no eating or drinking) (and I didn't downvote - appreciate your trying to answer)
Feb 12, 2019 at 20:59 comment added DanF @mbloch Did you read the two answers? The fast ends when it becomes dark, wherever they are at that time. Say it was dark in the middle of the flight, but on a westbound flight they enter an earlier time zone where the fast isn't over (for you). Your question specifies nothing about where these people came from. The rule in that answer applies to anyone in that situation.
Feb 12, 2019 at 20:53 comment added mbloch Also I was asking more generally. Not so much about these specific travelers. They are only the starting point of my question
Feb 12, 2019 at 20:53 comment added mbloch I am not sure what you mean. The fast ends at night local time. If they eat by day then there is no way they can have ended their fast. Or maybe I’m missing the point of your answer
