Intention to cleanup this article from undue self-references

edit

Most of this article is sourced to Delta. Unless someone objects, I intend to delete most (if not all) the material sourced directly delta.com, except that which is can clearly be justified by WP:PRIMARY WP:SELF. Reliable sources are supposed to be WP:INDEPENDENT of the subject. The level of self-sourcing to delta.com is WP:UNDUE and amounts more to WP:OR. This page should not be an advertisement WP:PROMO for Delta's frequent flyer program. This is an encyclopedia after all. --David Tornheim (talk) 02:14, 25 April 2019 (UTC)Reply

GRALISTAIR (talk) 02:20, 27 November 2019 (UTC) I will try and improve this articleReply

I have finally made a start - it may not be easy. There are plenty of blog references and YouTube but they may not be sufficient GRALISTAIR (talk) 02:17, 9 February 2021 (UTC)Reply

I have not removed all the self references to Delta's website. I have left them in place. However, I have added a lot of others such as Fox Business News, CNN, The Economist etc as reliable secondary/tertiary sources. I have also removed a couple of citation needed templates.

I have added quite a few secondary and tertiary sources and felt it was time to remove the clean up template. Of course further improvements can be made but I felt this was the right thing to do GRALISTAIR (talk) 14:28, 10 February 2021 (UTC)Reply

I have removed stub. It is clearly more than a stub at > 1000 words and quite well referenced GRALISTAIR (talk) 16:30, 9 January 2022 (UTC)Reply
