I am going to Orlando Florida, what are the safest of these airlines U.S Airways,Southwest,and United?

United, U.S. Airways, and Southwest are the only ones available on the day I am going to Orlando,Florida in March during spring break, Disney World here I come! I am however nervous about going on an airplane(which I have not gone on one in 4 years). I am going with 3 other people im my party and it will be a non-stop flight. If anyone has any experience in any of these airlines or advice on which airline I should choose, I would greatly appreciate it and maybe I will be able to calm down some of my nerves,lol!

All three airlines have excellent safety records, but out of the three only Southwest has never had a major incident. You can check the safety records for almost any airline from this website:

Yes, I vote Southwest. They are very friendly. Let them know you are nervous and all will be fine. Enjoy!

Delta

First of all don't worry! I have flown on an airplane roundtrip at least 2 times a year since I was born. I happen to love flying. Second planes are amazingly safe! A car is by far more dangerous. But I understand that you are nervous.
I usually fly U.S. airways and it is nice. I have never had a problem. I think that is what I would recommend, but you should also judge by the price and the amount of time in layovers. All of the airplane companies will probably be fine. Just enjoy the trip!!

They are all alright, but Southwest is the one that has the best on time record and it might be cheaper than the other 2

I would recommend southwest

All three are extremely safe airlines. If the ticket prices are similar, then go with the airline that offers a departure time that most favors you and your friends. However Southwest has the best in-flight service of the 3 airlines mentioned.

Have good time.
