<p>As a frequent flyer, the rule of thumb is that 25,000 miles (typical for a domestic ticket) is worth about $400. </p>
<p>My kids’ schools are roughly $60,000 and they charge 2.5% (I might be off - I did the calculation once and it wasn’t worth it, so I never bothered to look it up again). So that’s an extra $1,500, which would get you 60,000 miles which is 2 tickets with a bit of leftover. $1,500 for 2 free domestic tickets is a rip-off if I could get them for $800. </p>
