🗓️ Feb 2026 Flight | 💺 Prestige Sleeper | ✈️  B777-300ER

7/10 (🌕🌕🌕🌗🌑) Korean Air's signature service, Korean-style meals, and convenient lounge boarding were satisfying, but it was a flight where the limitations of the older B777-300ER and Prestige Sleeper seats were clear. Even within the same Prestige Class, the gap in quality depending on the aircraft and seat type was very noticeable.

🗓️ Jan 2026 Flight | 💺 Delta Main Basic | ✈️  A220-100

7/10 (🌕🌕🌕🌗🌑) With wide seats, a personal monitor, free Wi-Fi, and two beverage services, it was a quite satisfying economy flight for a U.S. domestic route. The seat selection restriction on the Basic fare was a bummer, but I could feel why Delta is considered a premium airline.

🗓️ Dec 2025 Flight | 💺 Prestige Sleeper | ✈️  A330-300

8/10 (🌕🌕🌕🌕🌑) The service was simple, but the wide-body A330's full-flat seats, priority baggage, and on-time arrival were satisfying. The location of the Jeju Airport lounge, the low privacy of the aisle seats, and the exhaust smell during engine startup were disappointing, but considering the price, it was a solid domestic Prestige flight.

🗓️ Dec 2025 Flight | 💺 Prestige Sleeper | ✈️  A330-300

8/10 (🌕🌕🌕🌕🌑) Even though it was a short domestic flight of just over an hour, the ability to use the lounge, priority boarding, and spacious full-flat Prestige seats made it highly satisfying. The in-flight service was simple with just drinks, and the older entertainment system was a pity, but for a domestic business class, it was an experience well worth the money.
