Traveling today for a religious Jew is quite different than it was years ago, and a simple airplane ride has come a long way. For example, food is readily available for a religious Jewish traveler, and kosher meals, snacks, drinks, and even alcoholic beverages can be had at one’s beckoning; a person is not lacking when he travels on a plane. When Rav Yaakov Moshe Kulefsky zt”l, the Rosh Yeshivah of Ner Yisroel in Baltimore, would travel, however, he refused to eat the plane food even if it had a proper hechsher and, instead, his wife would prepare him the requisite meals for his travels. On one occasion, Rav Yaakov was flying to another city for the purpose of meeting an important donor to the Yeshivah. The flight duration was a few hours, and since he wouldn’t eat the food being served anyway, his wife had prepared a sandwich for him prior to the flight. A short time after takeoff, when the Rosh Yeshivah saw that the flight attendants began to give out food trays to the other passengers, he opened up his hand luggage and took out the package that his wife had prepared for him.
