DonewithMarriott,

First, welcome to FlyerTalk. Please do not read some of the responses to your post as attacks. Participants on this forum are helpful, but can be quite direct in their responses.

Given your lifetime status and your status this year, you might want to spend more time on this forum. Over a course of many years, I've learned a lot, and I've helped others. Participating on this board is fun, and I consider it time well spent.

There are two possible reasons why your missing stay request was rejected:

1. Non-qualifying. As others have noted, only qualifying stays (as defined in the Marriott Bonvoy Loyalty Program Terms & Conditions) are eligible for points and elite nights. That makes sense. Marriott is willing to pay commissions to online travel agents or to provide points and elite nights to members -- but not both.

2. Mistakes by the hotel and the customer service center. Your Marriott Bonvoy number should be on your reservation when it is made. That increases your chance of a better room assignment. You should not have to show your card to the front desk. It's possible the front desk did not add your number properly, leading to no points or elite nights. And then, it's possible the customer service center incorrectly identified your stay as non-qualifying. In 2021, it took me two tries to have a qualifying stay added. The response to my initial missing nights request was a canned response that only stays booked through approved channels can be counted.

Given that you've reached Titanium Elite this year, I assume that other stays that you booked through your corporate travel department have posted properly. Either your corporate travel department did something differently this time, or you've been lucky with your other business travel reservations.

If it turns out be reason 1, then consider this a lesson learned. Talk to your corporate travel department. Reservations made through an approved Marriott channel should not cost your company more.
