Hello I am a novice when it comes to booking award travel. But I noticed that availability changes significantly when searching for 2 tickets vs 1 ticket. I am also looking to travel 11 months from now, so does that play a factor?

Basically I would just like to book 2 business saver tickets on a partner carrier from BKK to LAX for 80k miles or less. I just need the flight to return to LAX by Monday January 9. It can leave BKK either Sunday Jan 8 or Mon Jan 9.

Right now the only availability for 2 business savers is for BKK to LHR to LAX on 1/9/2017 (total travel time is 28 hours!). I booked this award for 80k miles each ticket for now but I can change it if something better comes up. Kinda of a long route, but at least it will be in business class all the way.

My question is: Can two different mileageplus accounts search at the same time for only 1 ticket and select an identical award at the same time? Or is there really only 1 business saver award for alot of segments which is why alot of them disappear when the search is increased to 2.

Are there any tips or tricks when trying to book 2 business saver awards?

Apologize for the lengthy post! Any help would be greatly appreciated.
