No matter what airline you travel on you have the same problems. i have tried several different airlines and had much worse customer service.
Do yourself a favor and Do Not put expensive items in your checked luggage including expensive bags, gifts, or clothes. If you do have expensive clothes try taking pictures and get insurance. Read every line on the website about children, special needs, or other concerns; and if you still have questions, email them and print out answer and take with you.
I always carry basic clothes in my carry on and have funds set aside for emergency clothes, hotel and other minor problems that can turn in to big disasters if you are not prepared. Seems over the top but I have discovered the being prepared is a lot easier than not.
