Audio shiur on EL Al pricing error by Rabbi Ari Marburger

Click Here for the Audio shiur of the Buisness halacha institute regarding the El Al pricing error. The shiur is  given by Rav Ari Marburger. He discusses weather its Onaah for those who purchased the ticket knowing at the time it was a mistake.
This is a psak from Rabbi Chaim Kohn printed in the Mishpacha Article.

Rav Chaim Kohn of the Business Halacha Institute says from a
halachic perspective, people were permitted to book tickets. “It’s a
strictly regulated industry, and it’s their obligation to bear the responsibility. The price they offer is their obligation — from a pure
halachic point of view, it’s their problem.”
