If the travel to your final destination consists of two or three successive flight segments, you may be able to obtain a lower fare if you split up your reservation and purchase a separate ticket for each flight segment. However, please note that traveling with separate tickets may lead to inconveniences and additional costs if your first flight is delayed or canceled.
If, for example, you book travel with SAS from Tromsø to Stavanger with change of aircraft in Oslo, SAS is liable for your travel all the way to Stavanger because you travel under a single contract with SAS. This implies that you have certain rights if your incoming flight to Oslo is delayed and you are consequently too late for your booked onward flight from Oslo to Stavanger. In such cases SAS will rebook you to Stavanger on our first available flight. Based on the length of time you must wait, SAS will offer you meals and hotel accommodation, even in circumstances where SAS could not have avoided the delay (even if all measures had been taken that could reasonably be required to avoid the delay) for instance when SAS cannot operate due to bad weather conditions.
By the same example, if you book travel with SAS from Tromsø to Stavanger, but choose to purchase tickets flight segment by flight segment, Tromsø-Oslo and then Oslo-Stavanger, the tickets for your travel may turn out cheaper than if you travel under one contract. However, please be aware that you do not have the same rights if irregularities should occur as when you travel under one contract. You do not have the right to be rebooked to another flight if SAS has taken all measures that can reasonably be required to avoid the delay. Likewise, you do not have the same right to meals and hotel accommodation if you arrive too late for your subsequent flight departure. It is therefore very important that you allow yourself ample time between scheduled arrival and scheduled departure, including sufficient time to pick up and re-check your baggage, and to submit yourself to new check-in and security procedures, all within the given time limits for your further travel.
