is this considered kosher?

Say I have an upcoming flight on another airline ( like an award redemption on an airline that isn't AA or AS). No lounge access using my Citi Advantage MC. But if I buy a refundsble ticket for 2 hours later , check in, go to the club, then cancel, would that work?

it sounds kind of desperate and pathetic, I admit. I can live with desperate and pathetic. But if it's not kosher or viewed as truly gaming the system then we will respectfully abstain.
