[International]My first name and middle name are joined together on the ticket. Will this cause problems when boarding? There is no problem with your name on your ticket as long as it is shown exactly the same on your passport excluding spaces in between.

Yes, it is completely normal and perfectly okay if your first and middle names appear "squished" together (e.g., JOHNDOE) on your airline ticket or boarding pass. This is a common formatting quirk caused by legacy airline reservation systems that lack a dedicated field for middle names or have strict character limits. When the system processes your Secure Flight data, it often merges the first and middle name fields into one continuous string. As long as the spelling is correct and the names appear in the same order as they do on your passport or government-issued ID, you will not have any trouble passing through security or boarding your flight. TSA and airline gate agents are well-trained to recognize this "no-space" formatting. You only need to worry if the names are in the wrong order (e.g., DOEJOHN) or if there is a typo in the spelling, as these can trigger a mismatch with your official travel documents and potentially lead to a denied boarding situation.
