    Editorial take: Delta SkyMiles Reserve Amex

    Only worthwhile if you actually use Delta SkyClubs, the access alone is worth the fee for frequent Delta flyers. The upgraded companion cert (can be used on First/Comfort+) is a big perk over the standard Platinum version.

    Editorial take: CitiBusiness / AAdvantage Platinum Select Mastercard
