There is nothing wrong of asking questions or making requests from your cabin crew during your flight, but of course, we can't expect them to address each and every of your concern. Some of those things you may ask may also be far beyond their scope of work or concern that it may need a different department to answer them. There may also be some questions you may ask that they would gladly answer you in complete detail.
Here, we run down those questions and requests that cabin crew members would answer or grant and wouldn't be able to.
