It did momentarily occur to me to try that, but since I was receiving all other types of email, I didn't think it necessary. I even went to other airline and shopping sites and manually requested emails to confirm everything was ops normal. Those emails were received as usual, and immediately. Also, this abnormality only started within the last week. That coincides with changes they recently made to their site, so I strongly suspect it to be on their side.

I only have this one email program installed on my phone and strongly desire to keep it setup that way.

Thanks for the suggestion.
