As Seatfrog is a last-minute upgrades service, availability of upgrades on your service are confirmed closer to your date of departure.
Seatfrog upgrades with LNER are currently available only on selected weekday services, Monday to Friday.
Services are selected based on two factors:
1. Availability i.e. if there are empty First Class seats available throughout the duration of the entire service.
2. Operational factors. We are currently operating on a selected number of services with more being added every week! The selected services may change from week to week, which is why your trip today may not be eligible, however, the same service may be eligible next week.
