Lounges are amazing to travel. I was traveling recently and i I had two stop overs I used the lounge keys in. The first one saved my ass because i had to do for the destination country with one of those stupid covid registrations. It was just not possible on my phone (i didn't do it at home because i was waiting for the PCR test result), luckily at this first lounge there were computers i could use!
The second stop over would be over 12 hours! Having the chance of hanging out in the Lounge was quite nice. Food was amazing, i could just take also a shower. In a 30 hours flying itinerary i managed to spend 0 dollars. Especially good because I was traveling with low cost airlines which give you not even water! 🙈😊
Edit: traveling from Europe to India. Using Belgrad and Abu Dhabi lounges.
