So I booked EU-CDG-JFK-Onward ticket with Delta.

First time booking with them. I put my first name in the first name field, middle names in the middle name field, and last name in the surname field. However, when the booking is confirmed all of my middle names have been put in the first name field on the Delta site, albeit truncuated my final middle name. Phone Delta and they say no issue.

However, the first flight is on AF metal. However, when importing my details from Delta they have putt my first and middle names (as held by Delta) as one word so like "MIKEDAVIDJOH".

My question is will this cause issues with AF? I am more concerned about whether AF8 will allow this on the JFK flight since it is the US with their TSA.

Any help would be appreciated. Thanks in advance.
