There are a lot of Boeing 787 in the air at any time. You can go to flightradar24.com, click the filter icon at the bottom, add new filter, then aircraft and as ICAO code you just enter B78*
and it will show you only this aircraft type.
The risk for an incident with any 787 at any time in the next few years may be higher that it should be. But the risk for one individual plane on one single flight is absolutely negligible. You're more in danger on your way to the airport probably.
Can you imagine having to teach your kids about these risks, help them to deal with them and prepare them for adulthood?
That would be so much work.
