Upgrading to Premium seating on TUI’s 787 Dreamliner is generally considered a high-value investment for long-haul travelers in 2026 who prioritize comfort and a stress-free airport experience. The upgrade provides a significant physical advantage: seats are roughly 20 inches wide with a 38-inch pitch, offering about six inches more legroom and four inches more width than standard economy. Beyond the seat itself, the value is bolstered by "ground" perks such as priority check-in, fast-track security, and airport lounge access on outbound flights from the UK. Once onboard, you are greeted with a glass of Prosecco, followed by a four-course meal and an amenity kit from brands like Rituals. You also receive noise-reducing headphones and a more generous 25kg checked luggage allowance. For many, the ability to board first and disembark quickly, combined with the extra "wiggle room" during a 10-hour flight to Florida or Mexico, makes the additional cost well worth it to arrive at the destination feeling more rested and less physically taxed by the journey.
