Litvish kiryas..to answer your question I could never bring myself to fly Lufthansa or buy German products. And if having a choice I avoid products from poland france ukraine russia etc.. Many major German companies are around today solely because of the slave labor they used to get through the war years whether you are talking about mercedes or puma some of these factories actually had killing grounds on premise.
Additionally, except for Kevarim,many Rabbonim (Rabbi Reisman very recently)speak out against visiting Europe for pleasure.(they also many times will suggest spending the same amount of time and money in Eretz Yisroel)
Aside from possible Sakanos nifashos and difficulties that could ensue by flying with a bunch of Jew haters,if given a choice of where to spend money why directly support the jordanian government and antisemites?The op obviously had his/her reservations as people don’t post about flying on delta or virgin atlantic
Snowbunny- Jerry Reinsdorf is openly proud about the fact that he is a Jew and has owned the bulls and whitesox for at least 20 -30 years. He also gives heavily to Jewish causes across the spectrum what antisemitism are you talking about? If you are talking about racist comments by some players a few years ago, it really does not have a reflection on the organization.
