£15–25 overnight to London sounds tempting, but read the fine print
National Express runs long-distance coaches from the Edinburgh area to England, including overnight EDI–London trips that commonly take 9–11 hours. Promo fares as low as £15–25 one-way are real, but usually only if you book early; last-minute prices creep up fast, especially on Friday and Sunday departures.
Despite what the journey planner suggests, many “airport” services now actually start from Edinburgh Bus Station on Elder Street or major city stops, not right outside the EDI terminal. That means adding a 30–35 minute tram ride from the airport (roughly every 7 minutes in the day, about every 15 minutes late evening) or the Airlink bus into town before you even see a National Express coach.
Direct National Express runs from the Edinburgh region to London, Manchester, or Newcastle often run only 1–2 times per day per route, so you don’t get train-style frequency. Some overnight services sit for 20–30 minutes at intermediate stops around the central belt before heading south, which is a big part of why the coach can take almost twice as long as the East Coast Main Line train to London.
Seats on the EDI–London run get called cramped a lot in Reddit threads, especially if you draw the aisle on a full departure. People also complain about disruptive intermediate stops at 02:00–04:00 for driver changes or pickups. If you’re planning to step off an evening arrival at EDI and straight onto a coach, remember that any delay over about 45–60 minutes can kill your connection because there might not be another bus that night.
Baggage rules catch people out: National Express typically allows one medium suitcase in the hold plus one small cabin bag, and extra bags on long routes like Edinburgh–London can mean paying at the stand. That’s different from many airlines that allow one checked bag plus a full-size cabin case, so if you land at EDI with two big checked cases, budget both money and time to sort it with the driver.
Regulars often skip the nominal airport option altogether and head straight to Edinburgh Bus Station, which has toilets, cafés, and indoor waiting areas that stay open later than the airport forecourt. Overnight coach veterans bring a neck pillow, eye mask, and their own snacks because catering on board is minimal and some drivers lock the luggage bay at short breaks. Plenty of frequent travellers only use National Express one way, then pay extra for rail or air back because 9–11 hours on a coach is enough for one trip.
Practical tip: Before you book, double-check the exact stop name in the National Express confirmation and cross‑check it against Edinburgh Bus Station vs “Edinburgh Airport”; then build at least 90 minutes from scheduled flight arrival to coach departure to cover baggage, tram into town, and a delay buffer.
