Our tech teams are working on the issues. Please call reservations for help with existing or future travel and use airport kiosks to check-in for flights. Sorry for the inconvenience. We appreciate your patience while get ithe issues worked out.

This, at 6:11pm, after agents on the phone two hours ago told me that nothing was wrong and that a supervisor advised to "reinstall the app" - which would make it fine.

That's very helpful to call in when you are actually inflight. Wow

I've tried the reinstall process. No dice. Had to have a SP agent check me in.

I'm inflight right now and can't get to anything easily. It's obviously all still dysfunctional.

Firefox + IE working now on delta.com
 

Didn't try Chrome or FlyDelta. Trips load, don't have a check-in at the moment. Looks a little funky, runs a little clunky.

App worked earlier today for my flights today, but I can't get it to log in now for my flight tomorrow.

It just keeps timing out and saying "Sorry, try again later"

Website lets me in, but it's creeping along. My trips will not load and online checkin is not working.

Ditto... Not working on mobile app, safari, or chrome... Think they would roll back this late of an upgrade was taking place... Down all day is absurd!

My last 2 trip I couldn't log into the app after my flight started until well after my trip. These were both trips where I had connections. A day later all was good.

@DeltaAssist while inflight?

I am thinking this is volume related due to IROPS at DTW and many other places.

Still can't log in on iPhone or iPad , web site locks up on the Desktop. It's been down all day has anyone tried the Medallion line?

I can log in, but I can't view my seats. Same with the app. Can't check flight status either.

Same here. Already upgraded, but couldn't pick a better seat.

I've been trying to check-in and get a mobile boarding pass for a domestic trip that departs tomorrow since 2:55pm today. Apps, web, nada. Kind of insane to have a 6+ hour outage on checking in and getting boarding passes for a global airline of this size.
