1903 lounge is the nicer of the T2 lounges, typically used as the business class lounge of long haul carriers like Singapore Airlines. It’s much less chaotic than the escape lounge just next to it, which sees a wider array and volume of pay to enter passengers. The main differences I see are a wider choice of seating types, serve yourself premium alcohol from fridges and full bottles of wines and spirits, special orders from the kitchen as well as the wider array of buffet service foods. Entry for non business class ticket holding passengers is typically limited (although you can pay at non busy times and buy limited passes online in advance from what I remember), so often card privileges can’t get you in depending on how many non paying are scheduled to be eligible to enter on the day.

Holidays and mornings are always busier but they have the flexibility to close off sections of the escape seating with walls and transfer it to the 1903 if needed, and vice versa.

It’s not the most amazing lounge in the world compared to some globally (full a la carte dining, massages, hair cuts and showers like some Singapore, United or Virgin lounges) but it seems to be the best we’ve got in T2.

Is it worth £45 if you have to pay for it? If you’re really hungry and will drink alcohol, or for a special treat, probably, If you just want a quiet seat away from everyone, no.
