How/Where do I report a business that makes illegal shipments?

There's a business in my area that makes shipments internationally to a specific country. However, the way they ship is by charging by weight or for specific items (electronics, etc.) Then, they tell you when and where to pick it up. Parallel to this, they find people that will travel to that country and offer $180 for each 50lb luggage they bring for them. The suitcase they give this is filled with the stuff from people who are paying to ship their belongings. This helps people to pay less to travel. My point is that in an airline, you are supposed to bring your own belongings and pack your own luggage, not third parties'. Also, when they are marketed as a shipping agency, they don't specify the method they use and how risky it is (They don't know the shippers entirely, they are strangers!).

Does anyone know how I can report this business? Do you find any other reasons why this could be illegal?

As an airport employee how easy is it to get on a plane without a ticket after getting through security?

I'm getting a job at the airport at the airside and i'm curious if people have done this before and how easy/hard it would be.
I'm sure some people must have attempted doing this, not that I'm lol. Just curious

Added (1). I SAID I'm JUST CURIOUS, lol I would never do that! I'm just wanting to learn about these things as its my first time working in an airport and i'm trying to teach myself and make myself knowledgeable on things like this and growing up. I'm 19 and its my first job in retail

I'm about to fly with United internationally. What do I expect? I'm used to flying with southwest?

United isn't as clear about things like southwest. We're flying from Nashville to Chicago and we having at 4 hour layover. Then we're fly for 13 hours to Japan.

How much is 2 checked bags? SW is free.
Is this assigned seating or can webpick where we wanted sit? I'm going with 5 people and I want to be with them but worried that's not happening.
Do you we have free Wi-Fi or we have to pay?
Is there usb outlets on the plane? I'm getting a battery bank just in case.
Do they provide complementary snacks and drinks and we have to pay for them.

Any other advice or tips for this airline and long haul flights?

What do I need? Flying with friends child from England to Greece?

I'm flying from London Gatwick to Corfu, Greece on the 27th of July with a friends child who is 15. Do I need a letter of consent from her parents or anything like that? The airline says 15 is an adult ticket so this won't be a problem however will it be a problem getting through security?
