If else else if in Jquery for a condition

Question

I am having a set of text fields where i am doing validation Say I am Having a field called "seats" this can accept value less than "99999".Meaning I should not able to enter the "99999" any thing less than that is ok. For that I wrote below if and else if . please tell me whether I am doing any thing wrong. I am confused a lot from morning whether it should be less than or greater than

if ($("#seats").val() != '') {
    setflag = false;
    alert("Not a valid character")
}
else if($("#seats").val() < 99999) {
    alert("Not a valid Number");
} else {
    setflag = true;
}
