Trans Polar made a demonstration trip to Stockholm on 13 June 1970—legal because it was without paying customers. The airline applied for permission to operate out of Sweden, but this was rejected by the Swedish Civil Aviation Administration (CAA) and appeals were rejected by the Ministry of Enterprise, Energy and Communications. The reason was that it lacked a permanent organization, did not have sufficient experience in large-scale charter operations and could not document that its charter operations would be based on their own resources. Despite the lack of permission, Trans Polar sub-chartered a round trip from Stockholm to London on 28 June. It then operated four flights from Stockholm to Rhodes, Palma de Mallorca and London between 4 and 6 July. Trans Polar claimed that they were flying courtesy trips and that the passengers had agreed to be compensated the part of the package trip which would have been paid to Trans Polar. The arguments were rejected by the CAA, who stated that this was a typical post-excuse and that in case of a courtesy trip the airline should not be collecting the fare in the first place. The incident was investigated by both Norwegian and Swedish police.[6]
The airline started negotiating a charter contract agreement with the Danish tour operator Spies Rejser in July 1970. Trans Polar offered the operator the use of two Boeing 720s for 55 million Danish krone (DKK), 10 million lower than the incumbent Scanair was bidding, which would allow Spies to transport 140,000 of their annual 250,000 passengers. As the first aircraft was bound to existing operations, Trans Polar would have to procure two additional aircraft for the contract, as well as receive operating permission in Denmark.[7] Trans Polar and Spies signed a contract in mid-August for one weekly service from Copenhagen to Gran Canaria, while another weekly contract was awarded to Maersk Air.[8] Negotiations for the main contract started on 5 September; Scanair had stated a minimum price it could accept, largely based on the fact that Spies did not have an alternative operator. The successful negotiations with Trans Polar also included an agreement with Spantax, who each could offer Spies 70,000 seats for the season. The contract brought annual revenue of DKK 25 million to Trans Polar.[9] To fly the operations, two ex-Aer Lingus Boeing 720s were registered on 16 October.[4] The company later signed agreements with the Danish tour operators Karavan-rejser and Danmarks Internasjonale Studentkomite (DIS).[10]
Trans Polar issued new shares worth NOK 825,000 on 25 November 1970. At the same time, the airline's shareholders issued guarantees to the bank for NOK 1.2 million. This was increased by NOK 300,000 in December.[11] The company was insolvent at this time, but the creditors chose to instate a lawyer as chairman and continue operations.[12] The airline met with its largest creditors on 25 February in an unsuccessful attempt to refinance the company's debt.[11]
Simon Spies, owner of Spies Rejser, speculated in February 1971 that he might merge his airline Conair of Scandinavia with Trans Polar, although he also stated that once his airline received new aircraft it would no longer necessarily need to charter aircraft from other airlines.[13] Trans Polar was subject to a lawsuit by a laid-off pilot which the airline owed NOK 26,600 in pay and compensation for him paying his own connection flights to reach Trans Polar charters. The company had issued several cheques and bills of exchange that had bounced and the pilot threatened to bankrupt the airline unless he was paid. The company responded that he would have a very difficult time bankrupting them and the press should instead write about the airline's future, which they regarded as very bright.[14]
The airline also owed NOK 15 million in installments to Boeing Commercial Airplanes for the first Boeing 720 aircraft. Representatives from Boeing met up at Copenhagen Airport on the evening of 17 May 1971 and removed the altimeter from the aircraft and informed the airport police that they had seized the aircraft by making it not airworthy. The 170 passengers who had bought trips through Spies were only marginally delayed because Conair was able to ready one of their own aircraft in three hours. The preparedness was due to Spies' concern of the Norwegian airline's inability to perform.[15] Trans Polar's managing director Knut Borgen called Boeing's seizure "a misunderstanding,"[16] but nevertheless Boeing took over formal ownership of the aircraft two days later,[16] and the aircraft was re-registered on 24 May.[4] The other two aircraft were at the time stationed at Dublin Airport where they were undergoing maintenance and could not be used as reserves.[16]
Spies canceled their contract with Trans Polar on 21 May 1971. Simon Spies stated that they had been "endlessly generous" towards the Norwegian airline, and that they had suffered numerous delays ultimately caused by the airline's financial shortcomings. Conair had taken delivery of five equivalent aircraft and the company was therefore able to operate its own flights. Trans Polar had plans to quickly return to operations: the two remaining aircraft would be returned to Aer Lingus and three new aircraft would be purchased. This would be financed through conversion of debt to share capital and new investments from various shipping companies. Borgen emphasized that the market price for leasing aircraft had fallen and that the airline therefore could operate at a lower cost with new leasing contract. Once the airline was back on its feet, he believed Spies would return as a customer.[16] Trans Polar informed its remaining customers on 22 May that it would terminate its flights.[10]
The airline unsuccessfully scrambled to continue operations. A contract with Drammen-based Hercules and its Hamburg, West Germany-based subsidiary secured Trans Polar new operations, this time flying guest workers between West Germany and Turkey four times per week. Tjøntveit claimed on 2 June 1971 that he had secured new financing from British investors, who along with Norwegian shipping companies would purchase newly issued shares in the company. He also confirmed that the two Boeing 720s would return to Aer Lingus and plans for two new Boeing 707 aircraft to be purchased in time for planned operations to commence on 2 July.[17]
