Would you mind sharing how much is the difference between Y and Y+ fares?
If this is only a few EUR or USD, it might be worth it - otherwise IMHO the product is too poor to pay the difference...
Well, TUI applies yield management in determining the price to upgrade from Economy to Premium Comfort. Price may range from EUR 80 to EUR 400 per person and leg.
The hard product is fine. A 2-3-2 configuration on a Boeing 787 is not too bad.
The soft product is a hit and miss. We had Big Momma serving our rows. In that sense, TUI reminded me of a typical US airline.
Moreover, Premium Comfort does
not give you a meal choice, priority boarding, lounge, or free advance seat reservation.
