Glad I started this thread - I thought I was the only one.... I hope Delta fix this issue.. The day before departure, I usually busy running around getting ready for my trip and would use my phone to check it. The last thing I want to do is to search for my passport number. Interestingly, with this repeated need to enter passport number, I am now able to remember my new passport number but still struggle with remembering the expiration date.

Just odd that they a section for passport info but they never use that data.
