Ok, so we are in the same boat basically. The i-485 instructions state that you are allowed to file before i-130 is approved if a visa is immediately available. But there is not a definition for that. Let's keep each other updated!
Hi! PD Dec 19, 2016, almost neighbors, i130 still pending, and considering concurrent filing too.
For exactly what you are asking, no. She has to wait for her AP to be approved for her to travel and her application not to be considered as 'abandoned'. If there is an emergency, she can get an infopass appointment and get an expedited AP filed and issued in a matter of days, but only for emergencies.
Now, to file for adjustment of status you have to wait until March, and depends if USCIS approves the use of chart b (I think they will, but you still have to wait, link: https://www.uscis.gov/visabulletininfo )
Now, about the concurrent filing, it is allowed by Uscis on several conditions, being the third:
"When permitted by USCIS (as described above in “Acceptance of Adjustment Status Applications”), your priority date is earlier than the cut-off date listed in the “Dates for Filing Applications” chart for your preference category and country of chargeability."
So, technically, you can file i485 and combocards, but have to wait for AP, and even approved AP, I would suggest to avoid traveling unless it is an emergency, because reentry is not guaranteed, and only as "paroled", Idk what that means exactly.
