Delta SkyMiles American Express cards are offering new cardholders huge welcome bonuses—but these windfalls might be a bit too good to be true.

From February 6 to April 2, 2025, eligible applicants for a range of Delta SkyMiles cards can snag up to 110,000 bonus miles. Many people might see a windfall like this as rocket fuel for their travel dreams—but it leaves me scratching my head over Delta's increasingly elusive premium cabin awards.
