A lot of applications will ask you when you will be available to work. Just don't LIE. If you are graduating May 1st, don't put "ASAP" on the app. Tell the truth and get your resume in. Don't lie about flight time also. If you have 750 hours when you submit your resume, but expect to have 850 when you graduate, do not fudge your application to reflect what you *think* you may have to make yourself look better because they are not stupid and will check these things. I know this seems like common sense, but people do it.
