Overthewing, sorry but we all due respect (since you could be one of the guys paying my bills) you are talking nonsense!
1) Overhead locker are designed to support weight, next time you fly look at the plackard you can find on the side.
2)
I stand to be told that the lo-cos have maintenance, training and general safety standards well in excess of the mainline airlines.
Indeed FR and U2 flight crew training departement have a really good reputation in the industry.
3)Maintainace is a requirement and all airlines have to follow the required steps, no one will do more than what is required.
You obviously don't know what you are talking about so please stop posting non sense!
How would you feel if I spit untrue judgments on your company/business?
