Heathrow BA flights compete with sub-30-pound Ryanair fares from Stansted on this 2-hour hop.
BA operates from Heathrow T5 with included baggage and meal service -- good value when sales drop fares to GBP 50-70 return. Ryanair and easyJet fight for budget passengers from Stansted and Gatwick respectively, with base fares as low as GBP 15 one-way. The real comparison is door-to-door cost: Stansted Express adds GBP 20+ from central London, while the Elizabeth Line from Heathrow is under GBP 13. London - Barcelona planning works best when transfer times and baggage rules are checked together.
Barcelona's El Prat T1 handles most international arrivals. The Aerobus runs every 5 minutes to Placa Catalunya for EUR 7.75, significantly cheaper than taxis (EUR 40). If you land at T2 (some low-cost arrivals), a free shuttle connects to T1 in 10 minutes. When booking London - Barcelona, benchmark this option against nearby alternatives for better value.
