They may have picked up more passengers but their reason for diverting was an oil filter problem. this can happen to any a/c. Just because this is a 787 makes it news worthy... NOT! S^&* Happens.
Exactly - a Delta A330 from Athens to JFK diverted to Amsterdam yesterday for hydraulic problems, yet it didn't make the news. (http://www.avherald.com/h?article=4640b047&opt=0)
Oil filter indication prompted the crew to divert for a safe landing...the systems worked. Now United, Boeing and GE will figure out what caused the issue and address it.
