I think there are three basic factors about how safe a plane trip is.

1) Type of plane
2) Maintenance
3) Training of crew

In case of 1) all major aircraft manufactures build excellent and safe planes. A Boeing, Airbus, Embraer etc. is state of the art and thoroughly designed and tested.

Factor 2) and 3) are way more important. There is a reason why Europe has a black list of airlines which are not allowed to fly to Europe because of low maintenance standards and questionable crew training standards.
