https://suitcasetheory.com/ Travel logistics for people who travel often — packing, airports, transit, bookings and the unglamorous mechanics of getting there without losing the day. en © 2026 Carryon Media Works Tue, 11 Aug 2026 09:00:00 GMT https://suitcasetheory.com/packing/the-one-bag-rule-is-a-constraint-not-an-achievement/ https://suitcasetheory.com/packing/the-one-bag-rule-is-a-constraint-not-an-achievement/ Travelling with a single bag is not about minimalism. It is about removing an entire category of failure from every journey. Packing Ivo Mercer Tue, 11 Aug 2026 09:00:00 GMT https://suitcasetheory.com/airports/liquids-rules-exist-because-of-one-specific-2006-plot/ https://suitcasetheory.com/airports/liquids-rules-exist-because-of-one-specific-2006-plot/ The 100ml limit is not arbitrary security theatre. Understanding where it came from also explains why it is finally changing. Airports & Flying Tomas Brenner Sun, 09 Aug 2026 09:00:00 GMT https://suitcasetheory.com/airports/connection-times-what-the-minimum-actually-assumes/ https://suitcasetheory.com/airports/connection-times-what-the-minimum-actually-assumes/ The minimum connection time printed by an airport is a technical figure with specific assumptions. Most of them will not apply to you. Airports & Flying Tomas Brenner Wed, 05 Aug 2026 09:00:00 GMT https://suitcasetheory.com/ground/overnight-trains-are-accommodation-and-should-be-priced-that-way/ https://suitcasetheory.com/ground/overnight-trains-are-accommodation-and-should-be-priced-that-way/ Comparing a berth to a seat is the wrong comparison. Compare it to a seat plus a hotel plus a transfer. Trains & Ground Ayaan Qureshi Fri, 31 Jul 2026 09:00:00 GMT https://suitcasetheory.com/booking/card-fees-abroad-the-three-charges-nobody-separates/ https://suitcasetheory.com/booking/card-fees-abroad-the-three-charges-nobody-separates/ Foreign transaction fees, ATM charges and dynamic currency conversion are three different costs, and only one is unavoidable. Booking & Money Greta Lindqvist Wed, 29 Jul 2026 09:00:00 GMT https://suitcasetheory.com/booking/what-travel-insurance-actually-declines-and-why/ https://suitcasetheory.com/booking/what-travel-insurance-actually-declines-and-why/ Most declined claims fall into a handful of categories, and almost all of them are avoidable at the point of purchase. Booking & Money Greta Lindqvist Sat, 25 Jul 2026 09:00:00 GMT https://suitcasetheory.com/stays/how-to-judge-a-hotel-from-the-listing-without-staying-in-it/ https://suitcasetheory.com/stays/how-to-judge-a-hotel-from-the-listing-without-staying-in-it/ Photographs are curated, ratings are inflated, and the useful information is in three places most people skip. Where You Sleep Greta Lindqvist Thu, 23 Jul 2026 09:00:00 GMT https://suitcasetheory.com/routine/jet-lag-has-a-direction-and-that-changes-what-works/ https://suitcasetheory.com/routine/jet-lag-has-a-direction-and-that-changes-what-works/ Flying east and flying west are different physiological problems. Almost all generic jet lag advice ignores this.

Packing Ivo Mercer Thu, 16 Jul 2026 09:00:00 GMT https://suitcasetheory.com/ground/rail-passes-are-usually-the-wrong-answer-and-sometimes-the-right-one/ https://suitcasetheory.com/ground/rail-passes-are-usually-the-wrong-answer-and-sometimes-the-right-one/ A pass wins on specific patterns of travel and loses badly on others. The break-even is easy to calculate and rarely calculated. Trains & Ground Nadia Halloran Sun, 12 Jul 2026 09:00:00 GMT https://suitcasetheory.com/stays/hostels-guesthouses-and-the-middle-nobody-books/ https://suitcasetheory.com/stays/hostels-guesthouses-and-the-middle-nobody-books/ Between a hostel dorm and a chain hotel sits a category that is consistently better value and consistently overlooked. Where You Sleep Nadia Halloran Thu, 09 Jul 2026 09:00:00 GMT https://suitcasetheory.com/routine/doing-laundry-on-the-road-is-a-planning-decision/ https://suitcasetheory.com/routine/doing-laundry-on-the-road-is-a-planning-decision/ How you handle washing determines how much you carry, which determines almost everything else about a trip.

Packing Nadia Halloran Wed, 24 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/toiletries-are-the-heaviest-thing-most-people-decant/ https://suitcasetheory.com/packing/toiletries-are-the-heaviest-thing-most-people-decant/ A washbag is mostly water by weight, which makes it the fastest place to lose a kilogram without giving anything up. Packing Solveig Rein Mon, 22 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/what-a-personal-item-actually-measures/ https://suitcasetheory.com/packing/what-a-personal-item-actually-measures/ The second bag is the most misunderstood allowance in aviation, and on strict carriers it is the only free one. Packing Nadia Halloran Thu, 18 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/packing-for-two-climates-without-doubling-the-bag/ https://suitcasetheory.com/packing/packing-for-two-climates-without-doubling-the-bag/ Cold and hot in one trip is a layering problem, and layering is a system with three parts rather than a pile of clothes.

Packing Ivo Mercer Wed, 10 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/shoes-are-the-volume-problem-and-there-are-three-answers/ https://suitcasetheory.com/packing/shoes-are-the-volume-problem-and-there-are-three-answers/ Footwear occupies more of a bag than any other category by shape rather than weight, and the solutions are limited and known. Packing Nadia Halloran Mon, 08 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/what-to-carry-when-the-checked-bag-might-not-arrive/ https://suitcasetheory.com/packing/what-to-carry-when-the-checked-bag-might-not-arrive/ Delayed baggage is a routine event with a predictable shape, and the entire cost of it is decided by what you kept with you. Packing Solveig Rein Thu, 04 Jun 2026 09:00:00 GMT https://suitcasetheory.com/packing/adapters-voltage-and-the-plug-problem-nobody-solves-once/ https://suitcasetheory.com/packing/adapters-voltage-and-the-plug-problem-nobody-solves-once/ Plug shape, voltage and frequency are three separate things, and an adapter only fixes the first of them.

Packing Ivo Mercer Fri, 29 May 2026 09:00:00 GMT https://suitcasetheory.com/airports/a-seat-map-tells-you-more-than-where-you-sit/ https://suitcasetheory.com/airports/a-seat-map-tells-you-more-than-where-you-sit/ Row numbers, blocked rows and the shape of the cabin encode information the booking page never states outright. Airports & Flying Tomas Brenner Sun, 24 May 2026 09:00:00 GMT https://suitcasetheory.com/airports/boarding-groups-are-a-loading-algorithm-not-a-status-ladder/ https://suitcasetheory.com/airports/boarding-groups-are-a-loading-algorithm-not-a-status-ladder/ Airlines sequence boarding to move a full aircraft through one door quickly, and the order tells you how the aircraft is loaded. Airports & Flying Nadia Halloran Fri, 22 May 2026 09:00:00 GMT https://suitcasetheory.com/airports/overbooking-is-a-statistical-bet-and-you-can-be-the-payout/ https://suitcasetheory.com/airports/overbooking-is-a-statistical-bet-and-you-can-be-the-payout/ Airlines sell more seats than exist because a predictable share of passengers never show up, and the mechanism has rules you can use. Airports & Flying Nadia Halloran Mon, 18 May 2026 09:00:00 GMT https://suitcasetheory.com/airports/delay-rights-depend-on-where-you-took-off/ https://suitcasetheory.com/airports/delay-rights-depend-on-where-you-took-off/ Passenger protection schemes are regional, not universal, and the one that applies is decided by the route rather than by the passenger. Airports & Flying Tomas Brenner Sat, 16 May 2026 09:00:00 GMT https://suitcasetheory.com/airports/fast-track-priority-and-lounges-what-each-actually-buys/ https://suitcasetheory.com/airports/fast-track-priority-and-lounges-what-each-actually-buys/ Airport upsells solve three different problems, and only one of them is time you would otherwise lose.
