Hello,
This issue is starting to be always more frequent that a guest sends the booking request but her/his credit card or documents are expired and the booking goes on hold.
The guest has 12 hours to update her/his credit card or documents.
This could work if the booking reservation will be for the 2 weeks away at least, but it can NOT work if the check-in is the next day.
I'd like to propose to Airbnb to give 2 hours maximum to the guest to update the data and in the meantime to allow the host to cancel the booking request anyway in order to keep the unit available on the market.
My last very unpleasant experience has been with a guest who sent the booking request the day before the check-in.
The credit card was expired and Airbnb allows her to update the data in the next 12 hours.
Because I manage 12 units I found out that her boyfriend in the meantime was looking for better deals.
I asked Airbnb customer service to contact her. They called her several times but she never answered.
Once the 12 hours passed and the booking request expired she immediately updated her data, after 3 minutes, wrote to me she was sorry about that and she asked for a better deal because at that moment there were only few hours left to the check-in...
The host can not be hostage of a disonest guest because in this case we lose both: the host and Airbnb of course.
Hope this issue will be solved very soon!
