updates for today:
LHR is cancelled
BKK is delayed again from 23:00 to 5:00
EWR is delayed from 00:30 to 15:00 (!!!)
JFK (001!!) is delayed from 00:45 to 5:10
Is there a mass exodus from LY by customers?
As for the comments above about "chareidim" I think there are 2 main reasons why they fly ELAL:
1. The halacha of או קנה מיד עמיתך,
2. Hakoras Hatov for the fact that (as a public facade) LY doesn't fly on Shabbos (everyone knows that they fly subsidiaries on Shabbos, possibly Cargo, as well as other חילולי שבת) however at least publicly, there are no LY flights scheduled for Shabbos and 1st day YomTov.
