Flights for 2 program trips

Hi my name is Aidan Lopez-Rivera. I am a sophomore in highschool looking to raise money for opportunities that will benefit my future. I am raising money to take a round trip flight to Washington, D.C and a round trip flight to New York City.
The first round trip flight to D.C is for an envision program that I was nominated for. Its a program for teenagers looking to go into stem(science, technology, engineering and math), law and leadership careers. I was nominated for this program, was accepted then I picked to go into the Law and CSI program. This money will be used to pay for the 2 tickets round trip to D.C. I will be in D.C for a week. These tickets together will cost $400.
The second round trip flight to New York City is for a summer job offer I got from a family friend to work in architecture. Everything besides the tickets is being payed for. 
I will need the funds fairly soon to secure my spot and make sure the cost doesn't rise.  I am really interested in these two fields and would like hands on experience with both so I can make a decision and pursue my dreams. This would mean a lot to me and absolutely benefit my future in tremendous ways. I will be absolutely so thankful. This is my only way of getting those tickets to participate in these opportunities. 
Thank you, 
Aidan Lopez-Rivera
