BWI to SNA or LAX- please help
 

Hello,
I am looking for discount/affordable flights from BWI to SNA or LAX California. Ideally I would like to leave on Friday afternoons and return on Sunday evenings. However I can take an additional day off or two. I will probobly be taking these flights about once a month. Can anyone please advise me on an airline that offers a last minute or reasonably priced option for these flights. I would really appreciate it. Thank you!
