Alaska Airlines will soon stop its 30-year tradition of passing out prayer cards to passengers with their flight meal.

The airline said the practice will end next week after receiving mixed reviews about the message the prayer cards can send to travelers.

"Some customers were comforted by the cards and some didn't feel religion was appropriate on the plane and preferred not to receive one," an Alaska Airlines spokeswoman Bobbie Egan told the Associated Press.

The prayer cards feature messages from the Old Testament book of Psalms and were started as a way to set the airline apart from competitors.

Now, Alaska Airlines leaders say they want to respect all their customer, including those who may not agree with the cards.

"Religious beliefs are deeply personal and sharing them with others is an individual choice," CEO Bill Ayer and President Brad Tilden said in an email announcement Wednesday.

In 2006, Alaska Airlines stopped serving meals in coach class. Since then, only passengers in first class would receive the Bible messages.
