Picture an April 17 departure out of Detroit and you land at Heathrow Saturday morning with the full weekend ahead. JetBlue is pricing that at $354, which is 62% below what this route typically costs. London in mid-April sits in a good window, past the grey of early spring, before peak-season crowds settle in. San Salvador, Guatemala City, and a deep domestic run fill the rest.

Travel Smarter

💡 Travel Tip: United States passport holders can use automated e-passport gates at major UK airports, cutting arrival time significantly compared to the staffed immigration queue.

💼 Travel Essentials: A travel wallet like the Zoppen Multi-Purpose Travel Wallet keeps your passport, boarding pass, and cards organized for faster customs and entry.

📱 Travel Tech: TfL Go, Transport for London's official app, shows live Tube, bus, and rail times across the city and handles Oyster card management in one place.

Destination Spotlight: London, United Kingdom

The South Bank stretches nearly two miles of walkable riverside from Westminster Bridge to Tower Bridge, and it gives a first visit a sense of the city's scale before you've committed to a neighborhood.

• East of the City, Shoreditch and Spitalfields offer independent shops, weekend markets, and street art that run counter to the postcard version of London most visitors expect.
• The official Visit London guide covers neighborhoods, events, and museum hours, and it is worth a pass before you map out your days.
• Mid-April adds daylight that stretches past 8 p.m., and the Royal Parks - Hyde Park, Regent's Park, and Green Park - are all within easy reach of central London neighborhoods.
• Borough Market sits a short walk from London Bridge station and serves as a reasonable first lunch stop, with vendors covering most of the city's food cultures.

Insider Tip: If you plan to use the Tube daily, load an Oyster card at the airport on arrival rather than relying solely on contactless; daily fare caps apply to both, but Oyster gives you a physical backup if your phone loses signal underground.
