AITA for losing my phone

Me (31F) and my husband (29M) just took a 8 hour transatlantic flight. We splurged at the desk and got those nice seats that convert into beds. During this flight I lost my work phone.

For some context, this was our middle flight, we already had been on a flight and had one more to go until our destination. I purchased my plane tickets through work and for the first flight I needed my work phone out just in case. Other than that I did not need my work phone at all but, I kept it on me. I kept my personal phone and work phone in the large pocket of my hoodie.

When we started our decent on our transatlantic flight I noticed my work phone was missing. When we landed and people started to leave the plane I called an attendant over to help us. After about 10-15 mins of them dismantling the seat they found my work phone.

Once we found my phone my husband would not talk to me he was mad at me and said it was my fault I lost it and that I shouldn’t have even of had it on me, which is true. But, I felt like this was an accident and that yes, I should’ve put my phone away earlier but, I found it in the end. Am I the asshole for losing my phone?

Info: we did not miss or were late to our final flight
