Your body uses vitamin D for maintaining healthy bones and effectively absorbing calcium. Not having enough vitamin D in your system may raise your risk of osteoporosis, bone malformations, cancer, inflammation and suppressed immunity. A simple blood test can give you accurate results and help you determine if your vitamin D levels are in the healthy range.
Delta Airlines requires that the make-up bag or carry-on luggage must not exceed 45 linear inches, with a maximum size of 22 inches in length, 14 inches in width and 9 inches in height.
You should check with your airline first, but most domestic airlines permit a carry-on piece of luggage that is 45 linear (total) inches. A common sized bag for carry-on luggage is 22x 14x 9. Most airlines have a carry-on weight limit of 40 pounds. International airlines may have different restrictions for carry-on luggage. Again, it is always best to check with your airline first to get their exact requirements. Airlines enforce all size and weight limits much more strictly now than in the past. Bags are weighed at check-in and many airlines have placed bag sizers at their gates.
