Name in airticket ordered wrongly
 

My name is the airticket is ordered differently than the name in my passport.
in my passport I don't have any middle name but 2 last names concatenated. But while booking the agent mistakenly entered the first part of my last name as my middle name.

example:
First name : Sam
Last name :JohnSmith
But in my airticket it is
Smith/ SamJohn, ie John is mistaken as my middle name. So my name does not match my name in the passport. The agent is unable to change the name.only option is to cancel and book again, but the tickets are not available.
Should I risk not changing the name??
please help!!

Thank you!!

I dont think you will have any problems. It looks like they have mistaken John and the middle name (in your example), however this would not affect your ability to check in or travel

Leave it, it's not an issue at all

Have faced this a few times myself, never had any problem travelling.
