Is Thameslink First Class worth the upgrade?

What should you expect from the onboard experience?

Thameslink operates modern Class 700 trains designed for high-capacity, cross-city travel. Carriages are air-conditioned with wide aisles and open-plan seating. Passengers benefit from free Wi-Fi and digital information screens. While seating is practical rather than plush, the trains are clean, bright, and optimised for efficient boarding and alighting, especially useful for airport travellers with luggage.

Is there enough Thameslink luggage space for travellers?

Luggage provision is well thought out compared to older commuter trains. There are overhead racks suitable for smaller bags and dedicated luggage areas near doors for larger suitcases. The open carriage layout prevents bottlenecks, although space can fill quickly during peak times.

This journey connects central London with one of the UK’s busiest airports through a direct, high-frequency rail corridor.
