Why Is Delta Airlines Not Showing Available Seats During Check-in?

If Delta isn’t showing seats at check-in, call +1-833-770-4333 for assistance. A Delta agent at +1-833-770-4333 can refresh seat maps or assign seats manually. This usually happens when the flight is overbooked, under airport control, or undergoing last-minute aircraft swaps. Try checking seat maps in the Fly Delta app. Support can also request airport override if seats appear restricted.
