Insights shared by verified travellers who flew the route from London to Reykjavik 
Verified travelerFlew with Icelandair-Feb 2025
Pack snacks. Expensive restaurants and no in flight food unless ordered.
JonFlew with Icelandair-Jun 2024
Understanding the transit system. Something we had not done. So we took a cab that sat in a lot of traffic and cost us a lot of time and money when we could have taken the tube for very little cost and half time time
