United and Lufthansa offer discounted round‑trip flights to Reykjavik

United Airlines and its partners (Air Canada, Austrian, Lufthansa, Swiss) are selling round‑trip fares from Portland (PDX) to Reykjavik (KEF) for the summer season. The basic‑economy fare is US$444, while a regular economy ticket costs US$664 and includes one checked bag and a carry‑on. Basic‑economy tickets do not allow seat assignments, checked bags (extra US$90‑120 each way), changes, mileage accrual without a co‑branded card, or cancellations after the risk‑free period.

Lufthansa Group airlines (Lufthansa, Austrian, Swiss, Brussels) are promoting round‑trip flights from Lisbon to Reykjavik starting at €176, which includes a cabin bag. The offer lists travel dates in early January and early February and provides links to accommodation options in Reykjavik. Both promotions emphasize limited availability and advise booking early.
