If you’re coming back from JFK, double check if the Elemis spa has reopened
All club and first passengers are entitled to get a free massage or treatment at the lounge but they get VERY booked up, so unless it eats into your plans, get to the airport in plenty of time and go straight to the spa to book something. Even the chair massages are a good use of 20 mins
If you’re getting a night flight back, you can have a full meal in the lounge and then sleep the whole flight without being disturbed for the meal service.
And in the biz lounge, they don’t keep champagne in the ice buckets on display but will bring it to you by the glass - just ask any of the staff and they will come back with some
If you’ve got a night flight, change into something fairly comfy, and as soon as the seatbelt sign goes off, turn your seat into a bed and put your earplugs and eye masks on
If you’re on a day flight, you can still turn the seat into a bed, and have a glass of champagne while you watch some movies
The refurbed plans have quite decent screens in club now so it doesn’t feel like you’re watching something on your phone
