Here’s your FT first: name another TR with CX F, SQ F, AND WN. Exactly. There are none!

I managed to an interesting one a couple of years ago:

YVR-DEN UA 1st
DEN-BOS UA 1st
BOS-LGA US 1st
JFK-ZRH LX 1st
ZRH-LUG LX (0D) Business
LUG-GVA car over the Alps
GVA-AMS DS
AMS-EDI KL
GLA-PIK FR
PIK-BSL FR

So, I had a mixture of United and US First, followed by the amazing SWISS First product with the new cabin design from JFK to Zurich. This was followed by a short hop across the Alps on Darwin Airline, which has aircraft small enough permitted to land at Lugano. Crossing the Alps was by car, and a few days later I went from Geneva to Edinburgh via Amsterdam on a mixture of easyJet Switzerland and KLM. Then Glasgow Prestwick to Stansted on Ryanair, 3 hour layover in STN, and Stansted to Basel on Ryanair. The latter two tickets cost 1 penny each, plus the credit card fee, so a total of GBP12.02. Weird!

I loved this trip report, sprinkled with references to reality (such as what you had for breakfast), which help to anchor the whole thing into something that everyone could relate to!
