college
 

Hello, does it matter what type of college i hold? Could it be easyest college (social work) if i want to apply for job in airline company? Do they accept aviation related colleges only?

Depends on the company.

Why waste your money? Get a degree that will get you a non-aviation job if you need one!

Here in the US it doesn't appear to be much of an issue what your degree is in, but I haven't the foggiest about Europe in general, and Czech Republic specifically.

Very few airlines are interested in your college studies. Mostly they are after your flying skills, so the licence you hold is the prime criterion in terms of qualifications. Almost all companies, these days, are also assessing interpersonal skills.

In Canada at least, it's advantageous (but not strictly necessary) to have a college diploma or degree, and it's a further advantage to have an aviation related degree.

It's a competitive world out there, so I'd say a college degree of some kind would be desired.
