Haha it's really not a problem! However, if you still really feel like it, there's a small scale symbol underneath the user's data. Click on it, and you should be able to figure it out from there
I had to put one of my guitars in the hold from Ireland to Scotland. It was in a hard case and the flight time was only about 40 minutes...but the guitar was SOAKED when I got it back! Luckily there was no real damage done but my lesson is well and truly learned!!!
To be fair, it was just a generic Thomann job - maybe a fitted case would seal better. I've also seen people wrap their cases in a tonne of cling film...that may be something worth thinking about!
