The budget airline forced to apologise for serving ham on a flight from Israel this week admitted it has happened more than once.
EasyJet said the wrong canisters had been loaded on to a jet at Luton airport which led to crew offering ham melts and bacon baguettes to passengers returning from Tel Aviv.
A spokeswoman said at the time that they had broken their own policy not to load pork products and that guidance had been reissued to all cabin crew members.
But easyJet has since admitted that the mistake has happened again after another customer complained.
St Johns Wood businessman David Abrahams said he was offered the sandwiches on both his outward and return flight to Tel Aviv earlier this month.
They shouldn't do this on a flight to Tel Aviv
"This wasn't a mistake," he said. "An announcement was made on both the outward and return flight. I was flabbergasted."
He also lashed out at staff training after one stewardess offered a ham sandwich to a Chasidic man sitting next to him.
"I thought it was so insensitive," Mr Abrahams said. "I was quite horrified. I couldn't believe my ears. They shouldn't do this on an airline going to Tel Aviv.
"There was no sensitivity. The staff didn't realise it would be offensive. They hadn't been trained."
An easyJet spokeswoman said: "It does appear that the mistake was made on more than one flight around the time of the original flight mentioned - easyJet takes this extremely seriously and has put the necessary processes in place to ensure that this cannot happen again.
"All easyJet crew operating the Tel Aviv flight are given a full briefing before each flight, that includes cultural awareness. We include such information as part of our cabin crew training courses."
● Budget airline Monarch is considering kosher meals on its flights. A spokeswoman said: "For scheduled flights, where meals are pre-ordered, we are considering the introduction of special meals, which could very well include a kosher offering."
