Traveling During DST Transition Week? Here's What Can Go Wrong
You're flying from New York to London on March 8, 2026. Your flight departs at 10 PM and arrives at 10 AM local time. But wait — the US just sprang forward. Did you account for that? Is your hotel booking for the right night? Did your connecting flight adjust?
DST transitions create a surprising amount of travel chaos. Here's what to watch for.
The "Missing" Hour (Spring Forward)
When clocks spring forward, the hour from 2:00 AM to 3:00 AM doesn't exist. If your flight is scheduled during that window, it may be delayed, rescheduled, or simply not exist. Airlines usually adjust their schedules, but it's worth checking.
The bigger issue: if you're traveling across a DST boundary, the flight duration on paper may not match the actual time difference. A 7-hour flight from New York to London might feel like 6 hours because you "lose" an hour to DST.
The "Duplicate" Hour (Fall Back)
When clocks fall back, the hour from 1:00 AM to 2:00 AM happens twice. If you're booking a hotel for "the night of November 1," make sure you're clear about which night you mean. Hotel booking systems usually handle this correctly, but it's a common source of confusion.
Connecting flights during the duplicate hour can be tricky. If your first flight lands at 1:30 AM and your connecting flight departs at 1:30 AM, which 1:30 AM? Always confirm with the airline.
Hotel Bookings
Most hotel booking systems handle DST correctly, but there are edge cases:
- If you book a room for the night of a DST transition, the system may show the wrong check-in time. Double-check.
- Early check-in or late checkout requests can get confused during the transition hour.
- International bookings across DST boundaries: make sure the confirmation shows local time, not your home time.
Ride Sharing and Taxis
Uber, Lyft, and taxi services generally handle DST correctly, but there have been reports of drivers being confused about pickup times during transition nights. If you're scheduling a ride for the night of a DST change, confirm the time in writing.
Calendar and Meeting Confusion
If you're traveling for business during DST transition week, your calendar may show meetings at the wrong time. A recurring meeting that was at 2 PM Eastern might suddenly be at 1 PM or 3 PM depending on which side of the transition you're on.
Before traveling during DST week:
- Check all flight times against the new DST offset
- Confirm hotel bookings show the correct local time
- Review your calendar for the week after the transition
- Set alarms manually — don't rely solely on automatic phone updates
The International Complication
Remember: different countries switch on different dates. If you're traveling from the US to Europe in late March, the US will have already switched but Europe won't. The time difference will be one hour less than you're used to.
In October, the reverse: Europe switches back first, then the US a week later. During that week, the time difference is one hour more than usual.
