Airlines · Saudi Arabia

Hi, I booked an Etihad ticket on their website for Dusseldorf-Abu Dhabi. In the first name field, I entered all my first names (something I never do and I regret it, but the site was confusing). Everything is spelled correctly, but the problem is that I just received my new passport and only my first two first names and the first letter of the third appear—there’s no trace of the last one.

I called Etihad, and of course, they tried to charge me $100 USD to remove that last first name. But I’m hesitant because usually, I only put my first first name and not the others, and I’ve never had an issue... So I’m wondering if having that extra first name, which isn’t on my passport, could get me denied at check-in. Thanks for your feedback!
