Poor. We weren’t able to check in online (for several hours until we gave up) for no apparent reasons although our passports were loaded successfully. When we were at the airport check-in, a rep helped us at the kiosk but she disregarded the KTN provided to her so we had to come back for it after being questioned by the TSA person…

Flight delayed by one day and everything was so disorganized by the airline.

All the food seemed to have onions. I don't eat onions. Anyway, everything else was great. The biggest downside was the underpricer company that purchased the tickets from ANA. Underpricer never provided the United Airlines booking number. ANA was a code share and all our flights were on United. I finally was able get booking numbers from Ujuted on X. They saved me from the upsales underwriter tried to saddle my wife and me with.

Due to turbulence there was no inflight service, which is very understandable, The flight is very short, and safety is more important. There was a bit of a delay with take off, but was to be expected with the rain.

Overall the experience was ok. My two complaints are that the food is absolutely disgusting. The movies in the flight to Japan were a completely different selection than the ones on the way back. So if you’re looking forward to watching a certain move on the way back, think again.

Hard to explain because we thought we were booking ANA airlines, not ANA operated via United, so we were disappointed, but for what it’s worth, everything went smooth and loved the movie selections. The food was okay, processed and full of preservatives, so vs what we were expecting with ANA it was different

The overall experience was ok, though there was certainly room for improvement. My husband was asked to check his carry-on bag at the gate due to claims that the flight was “full.” However, upon boarding, we observed ample overhead space and several empty rows of seats. This made the request appear unnecessary and caused some discomfort, particularly as he was the only passenger singled out for this procedure.

The flight was smooth, but there were not enough options for meals and I was given beef when I do not eat beef. The flight going was much better because we received more snacks.

Thankful for the staff who provided blankets cause the plane was quite cold and no way to adjust the airflow in the seats next to the bathroom.

Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled
