How Amex changes affect your points strategy

American Express’ recent Membership Rewards shakeup is a wake-up call for anyone who treats points as a safety net. As TravelUpdate reported, Amex changed terms that affect how accounts are managed, and as Gary Leff noted, new Amex cards now open separate MR accounts unless you manually link them. That small change can leave balances exposed when you close a card, so travelers who rely on pooled points to protect redemptions need to act now.

The practical effect is simple and immediate: don’t assume automatic pooling or protection when you cancel a card. TravelUpdate’s coverage of the policy update and Gary Leff’s analysis both show that combining accounts is still possible, but it requires proactive linking and a fresh look at retention strategies. With lawsuits and pricing scrutiny in other areas of travel — TravelUpdate’s hotel pricing piece reminds us that hidden fees and distribution practices can change the math — points flexibility matters more than ever.

Sparkflights deals right now make that math tangible. We’ve flagged Boston–Dublin roundtrips on Aer Lingus at $329 roundtrip (≈5.2¢/mi, about 48% below historical baseline), Los Angeles–Honolulu one-ways on Southwest at $199 (≈6.1¢/mi, 42% below baseline), and Chicago–Phoenix nonstop fares on American at $49 one-way (≈3.9¢/mi, 60% below baseline). Those cost-per-mile savings can justify keeping the right credit card open for perks and transfer partners rather than chasing a short-term signup bonus.

Looking ahead, factor card account structure into every application decision and watch airline program shifts. Frequent Miler’s reporting on potential Southwest Companion Pass changes and The Bulkhead Seat’s note on Southwest lounges mean loyalty benefits are in flux; combine that with Amex’s new rules and you’ll want clear records and a plan before canceling cards. Use cost-per-mile comparisons to judge whether a bonus or benefit is worth the annual fee before you lock yourself into an account mix you can’t easily unwind.
