I just tried this out...We currently do not offer zmanim for flights departing from KBP airport. Sorry.Also they say it will take about 2 hours for them to email the info for the flight I tried leaving from EWR
Ahh, The ole fasting on the plane after RH eh? I remember that deal. Annoying
Uman?
Yup
DO?
Looking forward though we should start an Uman DO thread.
I think that they just upgraded their system at myzmanin.comInflight Zmanim - MyZmanim.com
There was an existing site for this - http://www.chaitables.com/chai_air_eng.php?look=20130821. They only have one zeman for each (instead of a range) and seem to be in line with the later end of the range in myzmanim's chart. This has the advantage of being instant but my zemanim seems to be easier to use (you don't have to calculate adding X hours and XX minutes etc. to your departure time to figure out the zeman - you just keep your watch on departure zone. ) See here where they calculate the zemanim for the same flight.
