Europe's high-speed rail network is one of the world's best — Eurostar from London, TGV in France, Frecciarossa in Italy, AVE in Spain, ICE in Germany. But cash prices vary widely (€40 walk-up specials to €200+ for last-minute), and BA Avios short-haul Reward Flight Saver at £1 in fees can make flying genuinely cheaper than rail on some routes. Here is the 2026 framework for when each path makes sense.

Avios Reward Flight Saver: the points-flight equivalent
BA Avios prices most intra-Europe short-haul flights at distance-based rates with capped fees:
| Distance band | Avios (off-peak economy) | Reward Flight Saver fees |
|---|---|---|
| Under 650 miles (e.g., LHR-CDG, MAD-BCN) | ~6,000-9,000 Avios | £1 (~$1.30) |
| 651-1,150 miles (e.g., LHR-MAD, FCO-LHR) | ~9,000-13,000 Avios | £1 |
| 1,151-2,000 miles (e.g., LHR-DUB, LHR-AMS) | ~10,000-15,000 Avios | £1 |
For travelers anchored on Amex MR or Chase UR (both transfer 1:1 to BA Avios), this is the cheapest intra-Europe flight option.

The actual decision framework
| Trip type | Best path | Why |
|---|---|---|
| London-Paris (200 miles by air) | Eurostar | Heathrow ground transit + security ~3 hours; Eurostar 2.5 hours city-center to city-center |
| Paris-Lyon (260 miles) | TGV (cheaper than flying) | 2 hours center-to-center; flight is similar overall |
| Madrid-Barcelona (320 miles) | AVE (€38 advance) or Avios (€1 + 6k miles) | Same total time; price comparable |
| Rome-Milan (300 miles) | Frecciarossa (€39 advance) or Avios | Same total time; rail better for city-center stays |
| Munich-Berlin (340 miles) | ICE (€60 advance) or Avios via FRA connection | ICE 4 hours; flight via FRA 4-5 hours total |
| Brussels-Amsterdam (110 miles) | Thalys/Eurostar (€55 advance) | Too short to fly; rail 2 hours center-to-center |
| Paris-Madrid | Avios (€1 + 11k miles, 2h flight) | Train is 12 hours; flight + Avios saves 9 hours |
| Tokyo-Osaka (similar context, NOT Europe) | Shinkansen comparable to flight | Use Avios if available; both work |
The Eurostar exception
For London-Paris specifically, Eurostar is almost always faster (2h25 city-center to city-center) and more comfortable than any flight option. The London (LHR or LCY) + airport transit + security + flight + Paris transfer chain is typically 3-4 hours total. Eurostar saves ~1 hour and offers a more pleasant experience. The price premium (~€100-€150 vs €1 + 6k Avios for an intra-Europe flight) is offset by the time savings.

The Avios short-haul stack

- Earn Avios via Amex MR transfer (or Chase UR transfer)
- Book each intra-Europe segment as a separate Reward Flight Saver award (£1 each)
- Total cost: 6,000-15,000 Avios + £1 per segment
For a 5-stop European itinerary with 4 intra-Europe segments, this is approximately 36,000-60,000 Avios + £4 in fees. Combined with a one-way trans-Atlantic award, the total mile cost is meaningfully under what cash retail would be.
Bottom line
For trips under 350 miles, European rail is typically the best path — particularly London-Paris (Eurostar) and other high-speed corridors with good city-center connections. For trips 350+ miles or trips between non-rail-connected cities (Paris-Madrid, Berlin-Madrid, etc.), Avios Reward Flight Saver at £1 + ~10,000 Avios per segment is the cheapest path. The hybrid strategy works well: rail for short adjacent-country pairs, Avios flights for longer cross-Europe legs.
