Finnair started a trial with Airportr, a service allowing customers to check-in luggage at any central London address ahead of a Heathrow flight.

The service starts at £30 for collection and check-in of one bag, with a one-hour timeslot. It goes up to £40 for four pieces with a three-hour slot.

Airportr started with British Airways in 2016 and is available to all British Airways customers leaving from Gatwick (LGW) and Heathrow (LHR). It added American Airlines flights from Heathrow to the United States last year.

The service involves a driver who collects and weighs the bags, scans passports and boarding passes and places the luggage in a coded, tamper-proof case. Customers are sent IATA bag receipts after airport screening, around 90 minutes before their flights depart.

For the Finnair partnership, for flights from Helsinki (HEL) to Heathrow, there’s also an option for customers to have bags picked up from the airport and delivered to a London address.

“As an airline committed to innovation, we believe this trial with AirPortr will offer customers a smoother and easier journey, without having to personally take their baggage to the airport and spend time queuing at both check-in and security,” said Sari Nevanlinna, head of ancillary business, Finnair. “Based on the upcoming feedback we receive on this initiative, we’ll also look into expanding the service to other markets in the future.”
