Is it safe to travel in a plane with a newly born baby (one week old)?

Yes. At my overseas post as a navy pediatrician, i routinely discharged babies to the bus going to the airport.Mom & babe left japan for a month or so with relatives before returning & none voiced any concerns with the experience. Take care to avoid physical contact with the curious (too many germs)& have plans on where to seek care if baby develops a fever.
