A day-by-day log of credit card transactions from the Enchanted Princess sailing, comparing effective exchange rates by card, by country, and by day.
USD cost per 1 EUR, weighted by spend — lower is better (less markup off the market rate)
Amex Platinum was tried first at every merchant; a decline meant switching cards, almost always to Nordstrom Visa
Amex Platinum accepted vs. declined, by where the transaction happened — highest Amex acceptance first
Total USD posted, grouped by where the transaction happened
Total USD posted, grouped by merchant category
Effective EUR rate on each day of the trip, in chronological order
Every confirmed transaction plotted by date, one dot per swipe
Plotted on separate scales — EUR and GBP sit at different real market rates, so one shared axis would flatten the EUR spread to a line.
Every swipe on record, best rate first within each currency. All three cards on this trip carry no foreign transaction fee.
