Only ran into a few issues myself so far luckily, such as missing flights or mandatory pilot breaks as if they didn't know it was coming and put our flight on hold for 2 hours... uhh what!?
Besides that your 100% right with the trash food, extra paying for seats, bags etc. Its very expensive.
so ridiculous right? Customer service is always horrible, for a little person like me, they won't even help me put my carry-on luggage on the overhead compartments.
That's not right :( and no nice gentlemen to help you out? Crazy!
Usually some one eventually helps me once they realise i'm too short to do it myself! I do try though!
