Interline deals have been struck by Loganair with Thomas Cook Airlines Air France-KLM with four more pending.
The agreements enable passengers using the Scottish regional carrier to through-ticket and check baggage onwards where flights connect at Aberdeen, Edinburgh, Glasgow, Inverness and Norwich airports.
Loganair is close to signing agreements with Emirates and another three international airlines.
The Air Passenger Duty saving on flights from the Highlands and Islands can be as much as £78 per person if connecting onwards to long haul destinations, according to Loganair.
The Thomas Cook Airlines partnership provides long haul connections from Inverness and Norwich via Manchester to destinations including New York, Los Angeles, Boston, San Francisco, Seattle, Orlando and Las Vegas on a single ticket.
It also complements codeshare arrangements Loganair already has in place with British Airways and its partner airlines at Manchester, offering connectivity to transatlantic routes, including Chicago and Philadelphia, with onward connections throughout the US.
The deal with Thomas Cook Airlines will allow holiday connections from the Highlands and Islands via Glasgow to destinations including the US and the Mediterranean on a single ticket.
The same will apply to Emirates services to the Middle East and onward to Asia and Australia.
The arrangements with KLM and Air France will allow passengers from Loganair’s Highlands and Islands network to travel via Aberdeen, Edinburgh, Glasgow or Inverness onto KLM flights to Amsterdam and onward to destinations worldwide.
Passengers can also travel via Aberdeen and Edinburgh onto Air France flights to Paris Charles de Gaulle and onwards across the French airline’s global network.
Loganair commercial director Kay Ryan said: “These are exciting deals with some of the biggest names in international air travel, and they mean a better, joined-up service for our customers – as well as making it easier for overseas tourists to come and visit some of the beautiful places we fly to in the Highlands and Islands.
“Our brand strapline boasts that we’re Better Connected, and deals like these make that statement increasingly true.”
The latest announcement comes just weeks after it was revealed that easyJet’s global connections platform, Worldwide by easyJet, of which Loganair was a founder member, had added three more airlines and seven more airports to its membership
This platform enables customers of participant airlines to seamlessly connect with partner airline flights through a digital, virtual hub.
EasyJet also sells stand-alone tickets on behalf of partner airlines, including Loganair.
