I am a member of JetSmarter and have used the service for a flight in the EU. The speed of communication through the app was incredible with all the paperwork being done through via the app. The JetSmarter concierge also made the relevant reservations for my business lunch and it was faster than using my Quintessentially service. I very much see this continuing to gain traction and as their database grows it will also spin out more customers for their ad-hoc model. I am certainly renewing my membership in November again.
