I got one for last year, You'll just need to send your parents tax form in and they validate you based off of need. To reference the income on my moms tax last year was about $30,000 and they paid for my flight and Fee, They'll organize your flight and you'll need to check in via southwest(Its what they have used for all visits that have been funded by the academies sources) 72 hours prior to departure. If you have any other questions feel free to PM me.
Edit**
They might also need to change your NASS session because you aren't locked in until you make the payment. I was accepted for the 1st and ended up going to the 3rd.
