These are a bit sneakier as I haven’t really picked up on them but I am sure I will now!

Sometimes the British will use in when we would use on such as in a team (British) on a team (American).

Here are some other good examples of the differences:
British                                                                                     American
At the weekend                                                                      On the weekend                    
Talk to (American version is more politically correct)               Talk with
Different to                                                                             Different than
Near to                                                                                    Near
Off                                                                                          Off of

It’s the little stuff that makes the difference!

All the Best!
