Why Memorial Day Weekend 2026 Is Your Perfect Opportunity?
The long three-day weekend in May – Memorial Day weekend 2026 runs from Saturday, May 23rd to Monday, May 25th. For UK travellers, this represents a good window.
- Fly out on Friday evening, May 22nd
- Enjoy three full days in a US city
- Return on Tuesday, May 26th (using just one or two days of annual leave)
Destinations like New York, Boston, Washington DC, and Chicago are ideal for this timeframe. The combination of a holiday weekend and the start of the US summer season means airlines offer competitive fares to fill seats.
Booking tip: For last-minute deals, book 2–4 weeks before departure when airlines release unsold inventory. For guaranteed travel during Memorial Day weekend 2026, book earlier (February or March).
