I have a return BA Avios Y booking to Tel Aviv. The outbound was cancelled (like in Dec 2024 for a March 23 outbound) and I was moved to ElAl which provides a better service than the new Easy Jet experience on BA for the route. I thought it would be nice to get my return booked on ElAl too but BA said that while the BA flight is operational they won’t swop. (My return is on 16 June). I guess that:
a) I should not have hoped to hard, and
b) Being punished for hoping, as my BA flight is still operational, and they won’t move me!!!! (Yet)!!!

To book a seat call El Al centre in Düsseldorf. They answer fairly quickly and oblige with a smile (seems like a smile by the way they handle the call). However if it gets rerouted to Madrid/London/Tel Aviv, close the call and redial again.
