Minors traveling alone?

I'm 17 years old, and I want to travel with my 11 year old sister. We're planning to go to Austin, Texas. We have both been there 3 times now, with our dad, so I know the airport well. But, am I allowed to do this?

Would it help or be useless and a waste of money?

So I already have a BS in Meteorology, but want to be an airline pilot. I already have my private license, so starting up in part 141 program wouldn't work I'm told because I'm not starting from ground zero.

There's a community college that offers an AS in Aviation Management that I could mostly do online while working on my ratings at a private local flight school.

Do you think the AS in Aviation Management would help me in getting me hired at an airline in any way or is it a waste of time? You'd think it'd make you stand out more to have that coursework knowledge background, but I'm not sure.

Russian Visa - Help Do I need to book my hotel and flight before ordering my visa?

I'm planning on visiting Moscow and I've been gathering information on the visa to Russia website because I'm unsure on how it all works and as I have been looking at the form it asks for a hotel address. I have found the hotel that I'm going to book, so do I just use that hotel address before actually booking the hotel, or do I need to book it first? If I go ahead and order my visa first and leave the hotel option blank and then book my hotel after I have received my visa, what will happen at the airport? Do I tell them that I now have a hotel and provide them with the address?

Airplane mechanics: why would a plane have to burn off fuel before landing?

My local news just talked about a flight having to return to the airport after "mechanical issues with the nose gear", but then it said that the plane had to circle the airport for about an hour "ro burn off enough fuel for landing".

I'm curiois why would it have to burn off fuel instead of just landing? Especially if it turned around for mechanical issues.

Getting to a restricted ATP for airline hiring or a normal ATP. Best path

I already have my degree and a private pilots license.

I have 3 options…

1) Keep working towards my CFI at a local flight school, paying out of pocket and then instructing until I have 1500 hours.

2) There's a 2 year state college 2 hours north that offers a AS degree in aviation that is accredited for the restricted ATP. I could do the remaining aviation course work via distance, but would have to drive up once a week for the flying. I could get a restricted ATP at 1250 having done this program.

3) There's an in-town for profit college that offers a 4yr accredited aviaton degree. Once I hit 1000 hours, I could earn a restricted ATP after completing that program and instructing. The program is well over $100k though.

What's my best path you think? I feel like the cheapest would be to just earn my ratings through a local flight school and then instructing until I reach 1500 hours. Thoughts?
