UK261 applies to all LTN departures including easyJet and Wizz Air

Overview

London's fourth airport and easyJet's primary London base — single-terminal design, Thameslink to St Pancras, and Clubrooms lounge for Priority Pass holders.

easyJet hub and low-cost operations

Luton is easyJet's largest London base, handling dense European and Mediterranean leisure traffic from London's northern corridor. Wizz Air also operates significant schedules. For UK travellers chasing lowest fares, LTN often undercuts Gatwick on the same routes — but factor in Thameslink rail costs and easyJet baggage fees.

UK261 compensation applies to all flights departing Luton regardless of fare paid. A 3+ hour arrival delay on a UK-regulated flight triggers £220–£520 per passenger if the delay was the airline's fault.

Getting to central London

Thameslink runs to St Pancras International every 10–15 minutes at peak, taking ~30 minutes. East Midlands Railway also serves Luton Airport Parkway. DART shuttle connects terminal to Parkway station in ~4 minutes.

Compare LTN against Stansted (/airports/stansted) and Gatwick (/airports/gatwick) for your route — Luton wins on easyJet frequency; Gatwick wins on Virgin long-haul and lounge depth.
