I booked the tour about a week in advance, and it was very reassuring to be able to communicate directly with the tour operator via WhatsApp beforehand. Their responses were very prompt, and in addition to sending the e-ticket, they also provided thoughtful advice regarding rescheduling in case of cancellation due to bad weather, which allowed me to look forward to the day with peace of mind. On the day of the tour, the pickup arrived 10 minutes after the scheduled time, but it turned out that 10 minutes later was the original pickup time, so we arrived at the airport without any issues. Regarding seating, while everyone is guaranteed a window seat, it was a bit disappointing that I unfortunately ended up with a seat directly over the wing when checking in at the airport counter. Also, it was quite cloudy on the morning of the tour, and I was worried it might be canceled, but after waiting for the weather to clear at the airport, we took off safely. In the sky, we were able to witness the magnificent sight of Mount Everest, clear and cloudless, which moved me beyond words. The wing, which I had been concerned about, wasn't a significant obstruction to the view. After the flight, I received a commemorative certificate, and I was able to meet up with the driver smoothly for the return journey. The support from pre-trip assistance to on-the-day follow-up was excellent, and I'm truly glad I went. I highly recommend this to anyone who wants to see the spectacular views of the Himalayas up close.
