Unable to login to Delta.com on Safari on my iMac

This is happening on my iPad. Same issues. I have the latest updates and I use DuckDuckGo. Doesn’t work. Chatted with Delta for an hour. Opened a ticket. Who knows what will happen. I have to use my iPhone now to book tickets. Ugh.

I have a macbook air and tried logging in both yesterda (1/24 and today 1/25 with no louck Cleared cache and history in both safari and chrome and still same error as you all. Chatted with customer service and they put in a ticket. Fine to get in on iphone app with same credentials....this is beyon ridicuouls that they have had the problem for 3 weeks and no resolution....

I'm having this problem as well, with 2 different MacBooks and different versions of Safari.

I thought updating safari and MacOS would help on my newer MacBook, but nope. just chewed up 30 mins of my time and probably slowed my macbook down for a while.

Extremely inconvenient. You would think they would prioritize this fix as it directly hurts their bottom dollar if customers can't log in to buy tickets.

I also find the IHG website is a joke too, but let's not change subject.

Clearing Cache, cookies, etc, turning off ad-blocker, etc. all fruitless.

As of Feb 8 I am also unable to sign on to Delta with my Mac on Safari so issue is not resolved for everyone. I can sign on with my phone, iPad, my wife's much older mac, now can sign on using Firefox. Always love it when you google an obscure question and find an army of people with the same problem. Not sure - is this a Mac/Safari issue or a Delta issue?

I have been trying to figure out why i can log into Delta.com through Chrome but not Safari. I even took out an old machine that runs High Sierra and has Safari 13.1 to see if i could determine if this was a Delta problem or an Apple problem. Since I could not get on in Safari 13.1 i conclude a Delta change created this. In trouble shooting i tried all the suggestions made here and other posts.... - turn off Content Blocker, - allow pop-ups and turning on the Auto Play functions...... those changes did not work. After that i started going through the Safari Settings. I deleted a Delta entry in the "Manage Website Data" inside the Privacy Tab and that did not work. I then decided to turn off "Prevent Cross-Site tracking"....... and that is the culprit... I am now able to log into my Delta Account with Safari. My guess is that Delta wants this cross tracking for their partners and integrators so they have implemented a change in their system to make sure this can happen. Safari has had this Cross-tracking switch all the way back to Safari 13.1, and likely sooner, so it's not an Apple Issue. Not sure how i feel about being forced to allow cross tracking.

Works with DuckDuckGo

Same here and it is incredibly annoying.

Well….tried logging in on my iMac and it worked! The situation is resolved, at least for me, for now. Hopefully that is true for others!!

Issue is resolved for me as well, as of this morning. Had been unable to log onto Delta website using Safari for the past 1+ month. Hallelujah I hope Delta found a sustaining fix.

My issue with Safari and Delta is resolved-I’m hoping yours is as well.

I changed the setting to allow pop-ups and the issue went away.

I can open it without problems on my MacBook Air, but cannot on my MacBook Pro. Same OS, Same settings (as far as I can tell) different results.

Change the password!!! That works for me
