[Financial News] Travel creator Kwaktube opened up about his losses on an SK hynix investment while experiencing a first-class flight costing approximately 15 million won. He said he had invested a substantial portion of his available funds but was currently recording a negative return.
The YouTube channel “Kwaktube” released a video on the 7th titled “A Review of the World’s Most Expensive First-Class Flight.”
Kwaktube said he had been flying frequently because he was filming a long-term travel program. “I really wanted to try a truly good airplane at least once,” he said, explaining that he booked Etihad Airways’ The Residence from Japan to Abu Dhabi. The approximately nine-hour flight cost more than 14.9 million won. “I’m going for the biggest splurge of my life. Of course, it’s my own money,” Kwaktube said.
Even after taking his seat in the premium cabin, Kwaktube continued calculating the cost. “It’s 15 million won for 10 hours,” he said. Even excluding the various services, “That means it costs 1 million won per hour to ride this. This is a bit much.”
While discussing the flight cost, Kwaktube also brought up his stock investments. “I put almost all my stock investment money into SK hynix. I spent a lot,” he said. “I put nearly all the money I had into it. I kept buying more to average down.” He disclosed that his return at the time was “minus 14%.”
Even after mentioning the loss, Kwaktube indicated that he was considering buying more. Comparing it with the 15 million won flight, he said, “If it were me, I’d average down. I’d skip the flight,” adding, “If I buy just a little more here, I’m almost there. I mean averaging down on SK hynix.”
The 15 million won price continued to weigh on his mind during the flight. The Residence had a separate bedroom, private toilet and shower, but when Kwaktube became sleepy, he said, “I can’t sleep. I have to stay awake.” He resisted sleep, adding, “Every time I doze off, that’s another 1 million won lost.”
Although there was a bedroom, Kwaktube could not properly rest. After watching the film Mamma Mia!, playing games and taking a shower, he said, “I don’t want to keep talking about money either, but that amount keeps coming to mind, so I feel like I can’t relax.” He added, “I couldn’t sleep because I felt pressured to keep doing something.”
The premium-cabin experience ended after he arrived in Abu Dhabi. Kwaktube then had to take an economy-class flight to Istanbul and was told that his The Residence ticket could not be used to access the transfer lounge.
Saying it would be difficult to spend more money, Kwaktube said, “I guess I’ll have to sleep rough somewhere before I go.” In the end, he said, “I’ve returned to my normal routine,” and traveled to Istanbul in economy class for approximately four hours and 40 minutes.
