Coach travel is already one of the cheapest ways to move between cities in Europe and the UK, but even within the budget end of the market there is a wide range of prices. A few consistent habits — booking early, choosing the right operator, travelling on the right days — can meaningfully reduce what you spend. Here is how to find the cheapest fares and get more from every journey.
Book as early as possible
This is the single most effective way to save money on coach travel. FlixBus, BlaBlaCar Bus, National Express and Megabus all use dynamic pricing, where fares start low and rise as the coach fills. The cheapest fares — sometimes available several months in advance — disappear first, replaced by progressively more expensive ones as the departure approaches.
How far in advance to book depends on the route and operator. On popular corridors (London to Edinburgh, Paris to Barcelona, Berlin to Prague), seats at headline prices can sell out several weeks ahead, particularly around bank holidays and school breaks. For quieter routes, cheap fares often remain available until a week or two before departure. The rule is: if your plans are confirmed, book immediately.
Be flexible on timing
Coach fares, like most dynamic transport pricing, vary by day and time. In general:
- Midweek (Tuesday, Wednesday, Thursday) is usually cheaper than weekend travel.
- Off-peak departure times — very early morning or mid-afternoon — are typically less expensive than early morning rush, Friday evening or Sunday afternoon.
- Shoulder season (spring and autumn) is cheaper than peak summer and school holidays across most European routes.
If you can search across a range of dates on the FlixBus or National Express website, the fare calendar view shows how prices vary day by day — useful for spotting the cheapest departure window when your schedule is flexible.
Compare operators on every route
On busy corridors, multiple operators often compete directly, and their prices are not always in sync. For a London to Birmingham journey, for example, Megabus, National Express and FlixBus all run services, and the cheapest option changes depending on date, time and how far in advance you are booking. Do not assume your usual operator is the cheapest — check all three.
For European routes, add BlaBlaCar Bus and RegioJet/Student Agency to the comparison where they operate. Journey-comparison sites let you see options across operators at a glance, though you will want to click through to the operator's own site to book.

Discount cards and loyalty schemes
Several operators offer discounts for specific passenger groups that are worth knowing about:
- National Express Coachcard — available for students (with a valid NUS/ISIC card), under-26s and over-60s. Offers a percentage off most fares and can pay for itself quickly with regular travel.
- FlixBus has no standing loyalty programme, but runs promotional codes and sales periodically. Signing up for email alerts can catch these.
- Megabus does not have a loyalty card but runs occasional promotions and flash sales advertised on its website and social media.
- BlaBlaCar Bus occasionally runs promotional codes and discount periods, particularly for new users signing up for the first time.
Students in particular should check whether their university has a discount arrangement with any operator before buying a card — some institutions have bulk-deal partnerships.
Consider overnight coaches to save on accommodation
On longer routes, travelling overnight lets you save not just on the journey but on a night's accommodation. A cheap overnight coach from London to Edinburgh or Paris to Barcelona, arriving early morning, replaces both the travel cost and the hotel bill. Even if the overnight coach fare is slightly higher than the cheapest day option, the overall saving can be significant.
This strategy works best if you can sleep on coaches and if your accommodation at the other end is flexible about a morning arrival. For a full guide to overnight coach travel, see our night buses in Europe guide.
Travel light to avoid baggage fees
Most coach operators include one hold bag and one hand piece of luggage in the base fare, but extra bags are charged — and those charges add up quickly if you are making multiple journeys. Travelling with only what fits in a mid-sized backpack, taken as hand luggage, eliminates hold-bag handling time at boarding and any risk of extra bag fees. It also makes you faster to board, exit and navigate at the destination.

Watch for sales and promo codes
FlixBus in particular runs regular promotional sales — sometimes as low as one euro for a limited number of seats on selected routes — typically tied to new route launches, bank holidays or end-of-season clearances. These are unpredictable but real, and signing up for the operator's newsletter is the most reliable way to catch them. Third-party deal websites and travel forums also aggregate coach sale announcements.
Megabus has historically run similar promotions for new routes or capacity they need to fill. National Express discounts tend to be tied more to its Coachcard scheme than flash sales, but special promotions do appear around major events.
Split journeys carefully
On some routes, buying two separate tickets with a change in a hub city is cheaper than a direct service. This is more common with train-split ticketing, but can occasionally apply to coaches. The risk is that if the first leg is delayed, you miss the connection and the second ticket may not be usable — this approach is only advisable with a generous connection time and when you are confident about the route.
Frequently asked questions
When is the cheapest time to book a FlixBus ticket?
As early as possible is the consistent answer. FlixBus fares start at their lowest and rise over time. Midweek departures and off-peak times are cheapest; promotional fares appear occasionally and sell quickly.
Is it worth buying a National Express Coachcard?
If you travel by National Express more than a couple of times a year and qualify (student, under-26 or over-60), the Coachcard pays for itself quickly. For occasional travellers it is a closer calculation.
Can I save money by buying a return instead of two singles?
On National Express, return fares are sometimes cheaper than two separate singles — worth checking. On FlixBus and Megabus, there is generally no "return" product; you book two separate singles, and the cheapest approach is to check each direction independently.
Are coach fares cheaper than trains on most UK routes?
Yes, in most cases and especially for last-minute bookings. UK train fares rise steeply without advance purchase; coach fares rise too but rarely as sharply. On the most competitive corridors, coaches can be several times cheaper even when comparing advance prices. The trade-off is always journey time.
