1. Register here for Hyatt Bonus Journeys. You’ll earn 3x Hyatt points on stays of at least two nights when you checkout between July 20 and September 15. Don’t procrastinate just because you think you may not be traveling. Register anyway in case something happens.
2. The new AmEx Platinum changes are being probed and a nice hack has already surfaced: United and Delta frequent flyer members get discounted Clear membership of $119 even with no status, and you can add a Player 2 for an extra $60 which happens to exactly equal the $179 credit. So, your one Platinum credit is good for at least two people with almost no work.
Side note: It’s against the T&Cs to sell the Clear credit (I assume it is anyway), but you can almost certainly cash them out with a quick post on your Facebook page saying something like “I’m selling one year Clear membership for two people for $125.”
