@Sanjoy0 I read your post and I too am quite confused as to why you would be asking about how to attain Superhost status with regards to trips you are being "invited on by your spouse. Perhaps you can write back a bit more clearer post/question, so we can help because myself and this other host @Jeff158 both seem to have gotten the same impression from reading your post.
Superhost status badge is aquired by fulfilling all the requirements every 3 months as clearly written out by Airbnb on their website. Please go to the HELP menu on the ABB site and type in Superhost status. That will also help you as well. Again, this is only for those who hosts guests in their public ABB listing.
As a Superhost myself, I have written to ABB asking them to create a SuperGuest badge because I personally would like to see 4 of my former guests receive that.....as they were absolutely SUPER GUESTS! :))
If you feel that me or another host have helped you, feel free to click on the "thumbs up" button at the end of any post. Thank you so much.
