  • Works perfect
Style: Type B
Works perfect for giving just a little bit to a good deal more of length to the airplane seatbelt. It’s great to not have to rely on the flight attendants to track down an extender.

  • 737-700 (Type B)
Style: Type B
This item rescued me from being embarrassed on my last flight. I didn't have any problems on the other SW 800 Max8 and 737-700 flights. However, on my last flight the seatbelt was extremely snug. I took my seatbelt extender out of the pouch and it worked perfectly. My husband was so busy getting situated he didn't even notice I had use it. LOL I had a comfortable flight. I'm so glad I made this purchase. 😊 ... show more

  • It didn't work!
Style: Type B
I bought this because I'm on the bigger side and thought this was make traveling more comfortable. Tonight I flew for the first time with it, on southwest, 737-800 and it didn't fit. I struggled with it for 5 mins before the stewardess came over and said "sir, I'm going to need you to put that away now". Very embarrassing. ... show more

  • Fits SW seatbelt perfect! See update 7/2025
Style: Type B
Update 7.7.2025. Just flew SW last weekend and this does not work with the new planes. However, the seatbelts are quite a bit longer and I didn't need the extender. ORIGINAL REVIEW I felt so much better not having to ask for an extender. Just had it in my purse and voila, all was well. Worked perfectly on Southwest. ... show more

  • Fits Southwest 737-800MAX
Style: Type E
I purchased this belt for an upcoming trip on Southwest. Although the product description says that it fits Southwest 737-800 and 800MAX jets, it did not fit the belt on my flight. My flight was on a 737-800 which still had the older double hook belts. My return flight was on a 737-800MAX so it worked fine for that flight. I ended up ordering the other type of belt to have as I have another flight coming up and want to be prepared either way. ... show more
