Portr is looking to expand from its original London City Airport launch to other facilities following a sizeable investment raise of £3.3 million.
The on-demand luggage collection and delivery service - running under the AirPortr brand name - has recently started working with London Gatwick Airport's south terminal, with plans to target other destinations in the near future.
The round is being overseen by Hargrave Hale and includes two unnamed venture capital funds as well as a number of angel investors from the IT world.
The company launched in 2012 and secured its first airport partner in May 2014 (London City Airport).
The idea is that AirPort picks up a passenger's luggage from the arrival carousel at an airport and transports it to the customer's hotel, conference centre or other destination.
The company has already secured deals with the likes of British Airways to promote the service on flights heading into London City or London Gatwick.
Portr claims the signing of London Gatwick as its second location is a "major step-up" for the brand, giving it the opportunity to tap into 40 million passengers a year (a third of which are not transferring to other flights).
The reason for the arguably sedate roll-out since the company's formation three years ago is that such services can often take a lot of time to integrate into existing airport protocols, not least with security and handling issues associated with luggage.
To coincide with the funding raise, Portr has appointed Sean McDonald to sit on its board of directors. McDonald was previously senior vice president for global sales at Expedia Affiliate Network and is currently chief commercial officer at Travel Technology Research.
The luggage delivery sector has motored along in the background for quite some time, but there have been some recent deals to indicate that it could become another airport-based service with the opportunity to tap into the convenience end of the overall passenger experience.
Late last year, for example, Luggage Forward acquired rival brand Lugless for an undisclosed fee.
