Two Travel Deals Worth Checking This Week — and the Maths Behind Each

Two promotions landed this week, both expiring May 11. One is worth acting on. The other looks better in a headline than in a spreadsheet.

Here’s the arithmetic on each.

Amex to JetBlue: 10% transfer bonus

If you have American Express Membership Rewards points — the points you earn from spending on an Amex card — you can move them into airline loyalty programmes. That’s called a transfer. Your Amex points become airline points, and you use those to book flights.

Normally, transferring to JetBlue’s TrueBlue programme converts at a ratio of 250 Amex points to 200 JetBlue points. You lose 20% in the exchange. This week, through May 11, you get a 10% bonus: 250 Amex points become 220 JetBlue points instead.

So what does that actually buy?

JetBlue points are typically worth around 1.3 to 1.5 cents per point when you use them for domestic or Caribbean flights. With the standard transfer rate, each Amex point routed through JetBlue is worth roughly 1.0 to 1.2 cents. With the bonus, that climbs to about 1.14 to 1.32 cents.

That’s a genuine improvement — not spectacular, but meaningful if you already have a specific JetBlue flight in mind. The key phrase is “already have.” Transferring points without a booking in mind is how people end up with stranded balances in programmes they never use.

Why does JetBlue offer this? Airlines run transfer bonuses when they want to fill specific routes. JetBlue likely has summer capacity to sell and wants loyalty-programme transfers to help fill it. That’s useful context: the bonus exists because there’s availability. If you’re flexible on dates, the supply is probably there.

Verdict: Genuinely good if you have a JetBlue booking in mind for this summer. Check availability first, then transfer. Don’t transfer speculatively.

Delta gift card: $20 Starbucks kickback

Buy a Delta gift card of $300 or more before May 11, and you get a $20 Starbucks gift card. That’s a 6.7% return — if you value Starbucks credit at face value.

The catch is what you’re buying. A $300 Delta gift card locks that money into Delta flights at full cash prices. You’ll still earn SkyMiles on the flight itself, but you’re pre-committing $300 to a single airline.

If you were already planning to spend $300 or more on Delta this month — say, a flight you’ve already found and priced — this is free coffee. Take it.

If you’re buying the gift card to “save money” on a flight you haven’t identified yet, you’ve manufactured a reason to fly Delta. That’s the point of the promotion. Gift-card deals exist to pull forward demand and lock your spending into one airline. The $20 Starbucks is the bait.

Verdict: Fine if you’re already buying a Delta ticket. Skip if you’re not.

The pattern worth noticing

Every week brings transfer bonuses, gift-card promos, and limited-time offers. Most aren’t worth the time it takes to read the terms. The filter is simple: does this deal improve a purchase you were already going to make? If yes, act. If it’s creating the purchase, walk away.

The JetBlue bonus is the real one this week — especially for readers who looked at shoulder-season points bookings and spotted summer availability. Transfer bonuses and points devaluation are two sides of the same coin: airlines give more when they need to fill planes, and take more when they don’t.

Worth asking: when a transfer bonus appears, is it a sign the airline is struggling to fill seats — or just routine marketing? Learning to read that signal is where the real value sits.

One deal earns its slot this week. The other is a rounding error dressed as a promotion.
