How To Add A Companion To My Delta Air Lines Booking After I’ve Done Check-in?

To add a companion after check-in, call +1-833-770-4333 for Delta Air Lines support. Agents at +1-833-770-4333 can manually link your companion’s ticket to your existing booking. You’ll need both confirmation numbers and traveler details. Delta may issue a new boarding pass for both passengers. Always verify seat assignments and baggage allowances after the update.
