Flight time, the clocks, the weather and the one new form every traveler needs. A short guide for students and families on the March 2027 trip.
The group leaves Newark on Sunday evening at 9:30 on British Airways Flight 188 and lands at Heathrow at 9:30 the next morning. London is five hours ahead of Newark during the trip, so the flight itself is about seven hours. It is an overnight flight, which means a short night and a long first day.
The UK clocks go forward on March 28, 2027, the day the group leaves. Phones update on their own, but watches and alarm clocks may not.
Late March and April in London are cool and changeable. Heathrow averages for 1991 to 2020 show highs from about 53°F in March to 59°F in April, lows in the low 40s, and some rain on roughly one day in four. Pack layers, a waterproof jacket and shoes that are comfortable for walking all day.
American citizens now need an electronic travel authorisation (ETA) to visit the UK. It costs £20 and children need their own. Apply only through the official UK government site or app, since other websites may charge more. The ETA is linked to the passport used to apply, so check that the passport is valid before you apply.
The UK uses its own three-pin plugs and 230 volt power, so bring a travel adapter. Prices are in pounds sterling.
