There's a date on the calendar that's worth keeping in mind now, especially if you have one or more premium travel credit cards: June 30th. In fact, for many cardholders, it's an undramatic, but expensive deadline: the end of the first half of the year's benefits, at which point any unused statement credits disappear. No second chance, no extension, no roll over.

The math is so pretty in fact when you use these travel cards, they make an annual fee worthwhile. However, the math doesn't add up that fast when half of them go unused because life went busy and the deadline was seemingly too close to call. A quick review of your card benefits now could save you hundreds of dollars that would otherwise be lost at the stroke of midnight on June 30th when the first half of the year ends.

Below is a card-by-card list of items that are expiring and what you can do about them.

The Amex Platinum Two Credits Worth Checking

The Amex Platinum has a $895 annual fee, and a list of credits that balance that out. Two of those credits run on a biannual basis; that is, one half of the year's allocation is used up at the end of June.

The hotel credit is worth up to $300 per period (up to $600 yearly) for prepaid reservations through American Express Travel with Fine Hotels + Resorts and The Hotel Collection properties. The Hotel Collection is required to be a minimum of 2 nights. One of the purer ways to get the most value out of this stay is to book a hotel stay that falls in this period and qualifies for the $300 credit, but has not been used, and then travel to that hotel during the period.

The Resy credit runs differently, with $100 per quarter instead of half-year, so the Q2 window (April to June) also ends at the end of the month. Up to $100 is returned to cardholders for eligible purchases at Resy-affiliated restaurants (enrollment required). The hotel and dining credit closes out on June 30th when the reservation is confirmed at any participating restaurant.

The Amex Business Platinum Same Hotel Credit Business Context 

The Business Platinum is identical to the personal Platinum's hotel credit program, offering the same benefit ($300 per year, half semesterly) and the same two night minimum with Hotel Collection properties for prepaid bookings made through Fine Hotels + Resorts or The Hotel Collection on AmexTravel.com. If the June 30 deadline arrives without a qualifying booking, the business owner will be leaving $300 on the table.

The Amex Gold Resy Credit Closing Out

This is a good rewards card with strong rewards on dining and grocery items, but the Amex Gold card will also make you 100% points per year on spending at participating Resy restaurants (50% points per period, up to $50 per period, with enrollment), also. The Platinum tier is a worthwhile amount higher than Gold's $325 per annum, and the Resy credit is a real offset of the annual fee. This is nicely captured by a dinner reservation at a participating restaurant prior to June 30.

The Hilton Aspire $200 Resort Credit Resetting

The Hilton American Express Aspire Card is the highest ranking of the Hilton's co-branded line of cards, with an annual fee of $550, which is offset by the card's features. The most visible benefit is the Hilton Resort Credit, valued at $200 per booking period (every six months), that can be redeemed for up to $400 per year for Hilton Resort purchases, including room rates.

This credit rolls off of cardholders who are staying at a Hilton at a qualifying resort. If you're not rushed to travel, be sure to review Hilton's portfolio for resorts that accept this offer; you might be able to book a future stay at a discounted $200 until June 30. Luxury Hilton brands like Conrad, Waldorf Astoria and more often than not the other luxury brands are eligible for points redemption, and Hilton's award pricing system makes for interesting combinations when you compare it to the resort credit.

Three separate semiannual credits with Chase Sapphire Reserve

The Chase Sapphire Reserve carries an annual fee of $795 along with a thicket of benefits that include three different credits and each resets at the end of the June term.

What's expiring:

• One of the biggest single credit values in the program, the Edit hotel credit pays up to $250 per period ($500 per year) for prepaid hotel stays of 2+ nights booked on Chase's Edit booking platform.
• Sapphire Reserve Exclusive Tables credit: Up to $150 per period ($300 per year) when dining at participating restaurants that are part of Chase's Exclusive Tables dining program.
• StubHub and viagogo credit: Up to $150 per period ($300 per year) for StubHub and viagogo purchases helpful for those going to a concert, sports game or theater show before June 30.

All of these credits are non-rolling and unrelated. A Sapphire Reserve cardholder who has not redeemed any of these three benefits has up to $550 they could use within the next two weeks.

Why This Happens And How to Avoid It Next Time

The answer to why so many cardholders fail to capitalize on these credits has nothing to do with being careless, but rather because premium travel cards have long and complicated benefit packages. It's the combination of the different reset cycles and options such as hotel, dining, airline, subscription, and shopping credits that demand active management to get full value from a card.

The easiest system is the straightforward approach: At the beginning of each six-month reporting period, record which credits are offered and if there are realistic opportunities to utilize the credits within the six-month timeframe before they close. The reminder on the calendar is set to mid-June and mid-December, two weeks before each reset, allowing plenty of time to act without haste.

The Bottom Line

One of the most overlooked value opportunities with owning a premium credit card is the semiannual credit reset on June 30. Some of the top statement credit cards, such as the Amex Platinum and Amex Gold, Hilton Aspire, and Chase Sapphire Reserve, feature use it or lose it statement credits in each six-month period and the total amount of these statement credits can add up to more than $1,000 across multiple cards. 

Now is the time to review your accounts, see if you've any unused credits and make qualifying purchases before midnight June 30, or those credits will disappear.
