Ha! just this second posted another thread if any body remembers the website that checks routes
Had a KE fight that left Friday 10:00 AM and arrived 10:00 AM in NY. Chabad Shaliach in Seoul (great Guy) told me that I might be flying on shabbos. I checked that website and sure enough it flew upwards to Russia and flew thru shabbos for approx 15 minutes. Not to get into details, but my Rov told me its ok based on numerous circumstances (not for now) and in the future I should be careful about booking such a flight.
On a side note, I met what appeared to be a serious frum elderly couple, who the husband was sitting and learning the whole time and she woudnt look at me etc, and I told him this flight flies on shabbos, and he replied that I dont know what Im talking about. I tod him Chabad Rabbi who lives here knows this flight and told me it flies on shabbos and we verified it by tracker. "Eh, you know Chabad rabbis and their mishagasin"...
(im sure he had no problem eating by chabad rabbis) I showed hm on Google that the Star K has a whole article about such flights and specifically quotes this KE flight...."Eh Star K Modern Orthodox Rabbis, what do they know")
Oh well, sometimes you just go tot know when to give up and let them win their arguments...
