Passport doesn't match ticket

Usually middle names being left out or an initial instead is a non issue. I’m not sure about a misspelled middle name. I do know a non-matching first name, even if an usually accepted nickname, is often rejected.

My passport has my middle name. My airline tickets don't. No one has blinked.

As long as your first and last names match, you'll be fine.

In many countries, giving people middle names is not common. So it's not an expectation. I have had airline tickets where they run my first and middle name together, or just have a few letters of the middle in there, or no middle at all.

For years United tickets have run my first and middle name together and no one in any of the international airports I've passed through has ever stopped me or said anything. Instead of saying, for example: Susan Ellen Smith (my passport), United boarding passes always say Susanellen Smith. I sweated this extensively when it first happened, including making calls and sending emails. United said they couldn't change it at that time, and thankfully it's never been a problem since. I've flown through Italy, Germany, France, Netherlands, Egypt, Turkey, and the US with this "misspelling" on boarding passes and so far so good.

My son and I were booked on flights via Delta Vacations in December and our tickets were issued like this "Lastname PartialfirstnameMrs." and "Lastname PartialfirstnameMr."
However, I don't think anyone even looked at our boarding passes at any point. We scanned them, they beeped appropriately where they needed to and and it wasn't ever a problem.

I had a similar issue several years ago (in Korea) where my middle name was misspelled. They fixed it and reissued the ticket, no problems.

I was flagged in Munich because my ticket didn't exactly match my passport. Ticket only had first and last name. I just had to speak to an agent and they waived me on.

My last name has a hyphen. Over the years, I've noticed some software that various businesses use drop the hyphen. I often sweat over it, but I have yet to have a problem when Ii show up at the airport!

What we don't know, but perhaps can imagine, is what validations are being done behind the scene, checking passenger names against such things as do not fly lists, etc. How a name appears on boarding passes may be more of a display issue - it may appear correctly on an agent's screen when you check in, but be truncated or combined when printed.

So it's critical that you enter your name exactly as it appears on your passport. I don't see how an airline's system could mangle a middle name - it should just be reflecting what was entered.

I have a friend whose surname is Dutch and is listed correctly on her passport and DL like this

Van space Surname

Recently her airline tickets showed her name like this: Vansurname. It wasn't an issue.

How did that happen? Didn’t you buy your tickets on the airline website or app and thereby do your own typing? Or did a travel agent do the typing?

That you don’t have your middle name but instead an initial really shouldn’t be an issue. I would contact the airline about the misspelling of your husband’s name. I hope everything goes well for you.

This reminds me of the time a TSA agent gave my husband and I grief over his ticket - my husband is the fourth in his family with the same name, and on his birth certificate and passport it's IV. Maryland's motor vehicles department only issues driver's licenses with 4TH (or 3RD, etc). I had no idea, we'd flown internationally for our honeymoon so those tickets were with IV, we flew domestically about 6 months later and I'd booked them and used IV. Didn't think about it at all, and my husband didn't use his passport to fly just his driver's license. Took forever to get through, I don't know if the agent didn't know his roman numerals or what.

I also had a slight freakout when I booked our tickets on Icelandair, they changed the IV to Iv, and I contacted them to make sure it was ok (they said it was fine, just their software).
