Safari 4.0.4 vs, 4.0.3
I still can't fully access delta.com with Safari 4.0.4 on my MBP or iMac..BUT my partners new MBP has Safari 4.0.3 and Delta.com works just fine.
I'm not sure why this problem has not been addressed/fixed by Delta web support but I downloaded Firefox and all seems to be OK. I wish Delta would fix the Safari problem.
