Icelandair, former Loftleidir (in Icelandic: airlines) has made it into a flourishing business to offer passengers to fly between America and Europe via Iceland, either changing planes quickly and effectively right away in Keflavik, or also with a stopover in Reykjavik. Earlier Icelandair flew only with Boeing 757 planes, but now they also have bigger Boeing 767s as well as new, smaller Boeing 737-MAX8 planes.

Continuation to the picture above: Just as our Icelandair B767 had landed and was taxiing towards the terminal building at Keflavik, a B757 of Icelandair landed next - seen here right on top of the wing of out 767. This is typical of Icelandair's strategy. Planes from all over land at Keflavik more or less at the same time and are also leaving shortly, so that there are a couple of short changeover periods per day at Keflavik. Many passengers like the short stops and smooth transistions from plane to plane "midway" over the Atlantic.

Icelandair's Boeing B767 TF-ISW after just arriving from Helsinki and unloading passengers. Icelandair has a cooperation agreement with Finnair and Finnair has been very effective in getting Asian passengers to use Helsinki as a gateway. As a result, also Icelandair often has to use bigger B767 planes rather than the older B757s on the Keflavik-Helsinki route. More than 3 million foreign tourists, most of them from Asia and many of them flying via Helsinki arrive now annually to Reykjavik. Picture by Ilkka Siissalo 18.5.2018.

Icelandair B757 TF-ISJ called "Keillir" has just arrived from Reykjavik to Helsinki-Vantaa airport in Finland. Keillir is already an old plane. It was delivered to Iberia in August 1999 and before Icelandair it has also flown in the colours of Varig, ILFC, KrasAir of Russia and I-Fly of Russia. Icelandair took it in their fleet in December 2015.

Earlier Icelandair flew with only B757 aircraft. Then came the bigger B767s and then beginning in spring 2018 also the smaller B737-MAX8s. This is one of the new B737s, TF-ICE. Icelandair has ordered nine 737 MAX 8 and seven MAX 9 machines of a totally new generation with much less fuel consumption and they will shortly be replacing at least part of the older B757s.

TF-FII "Eyjafjallajökull" is a Boeing B757-208 which was delivered to Icelandair already in 1990. It has been several times leased out to other companies, including bmi, Air Mediterranee, Air Niugini, SBA Airlines and TACV. From 11/2018 it is again at TACV, but here it was still flying for Icelandair. It's next journey right after taking this picture was a trip to Helsinki.
