Funny this is brought up after not so long ago it was discussed throughly over an incident where LY flew on Shabbat.

To make a long story short, the airline was on the verge of losing the religious customer base and out of their own free will signed an agreement to avoid a boycott. They had a chance to open a new page and start flying 7 days a week and turned it down for their own reasons. This was under no government regulatory or other political reasons - probably pure business.
