A veteran travel journalist recently learned the hard way that the International Date Line doesn't care how many years you've been doing this job. While booking a Dallas-to-Sydney trip for himself and his mum, he locked in two business-class seats on Fiji Airways for 80,000 American Airlines miles each — and completely forgot that flying west across the date line means you land two calendar days after you take off.

The plan was ambitious: a near month-long run through Fiji, New Zealand, Australia and Hong Kong, kicked off with a three-night stopover at Likuliku Lagoon Resort in Fiji's Mamanuca Islands. But when he sat down a week before departure to write out the itinerary, reality landed: the flight departing Thursday arrived on Saturday, while the resort booking and pre-arranged boat transfers started on Friday. With the rest of the trip locked in, there was no room to shift anything by a day.

Fixing it wasn't cheap or easy. Fiji Airways wouldn't move the flights, and American Airlines' only option was to cancel and rebook. By then, award availability had dried up. The sole business-class seat leaving on the right day departed from San Francisco rather than Dallas — still 80,000 miles — so he grabbed that for his mum and cancelled the rest, getting the miles back instantly. But an economy seat on the same flights was oddly priced at 100,000 miles, more than the premium cabin, which he rightly refused to pay.

After days of striking out with transfer partners and cash fares, the rescue came from an unexpected corner: the Chase Travel portal. The flight qualified for Chase's Points Boost, valuing points at two cents each. His 158,540 Ultimate Rewards points covered $3,170.80 of the $4,066.50 fare, and he paid the remaining $895.70 in cash. Not the textbook-best redemption, he admits, but it put him next to his mum up front with a glass of Champagne instead of stuck at home.

His takeaways apply to anyone booking long-haul trips: always check which day you actually land when crossing the date line, keep tools like Seats.aero handy for spotting award space, know your credit card's travel protections and transfer options before you need them, and give yourself a deadline before burning points in a panic. And if the worst happens, flexibility — even a pricier gateway city like San Francisco — can be the difference between salvaging a trip and losing it.

For travellers eyeing Fiji as more than a stopover, the story is also a decent plug: three nights at Likuliku and time in the Mamanuca Islands were, in his words, worth every minute of the stress. Just double-check your calendar before you book the boat.
