The article presents several factual claims, some of which are verified, while others require further validation. The claim that Gisborne Airport in New Zealand has a railway line crossing its main runway is accurate and supported by multiple sources. However, the frequency of train crossings, stated as '15 times a year,' lacks specific verification in the sources consulted. Additionally, the article mentions safety coordination between air and rail traffic, which is corroborated by sources describing the operational challenges at Gisborne Airport. The section on Istanbul Airport's pricing lacks supporting evidence, making these claims less reliable. Overall, while some key facts are accurate, others need more robust sourcing or clarity.

The article primarily focuses on the unusual feature of Gisborne Airport and the high prices at Istanbul Airport, without providing a broad range of perspectives. It lacks input from aviation experts or local authorities who could provide additional insights into the operational challenges and safety measures at Gisborne Airport. The piece could benefit from a more balanced view by including testimonials from passengers or pilots who have experienced these airports. The mention of Istanbul Airport's pricing feels somewhat disconnected from the main narrative, suggesting a lack of balance in topic focus.

The article is generally clear and straightforward, with a narrative that is easy to follow. It uses simple language to describe the unusual characteristics of Gisborne Airport and the pricing at Istanbul Airport. However, the transition between topics is abrupt, particularly when shifting from discussing Gisborne to Istanbul, which may confuse readers about the article's main focus. More cohesive structuring and clearer delineation between separate topics would enhance clarity.

The article references the Daily Mail and an unnamed Facebook post, neither of which are directly cited, reducing source credibility. The inclusion of Italian newspaper Corriere Della Sera and L’Economia for the Istanbul Airport pricing adds some authority, but these are not directly quoted or linked, limiting their reliability. The story would benefit from more authoritative sources, such as official statements from Gisborne Airport or interviews with aviation experts, to enhance credibility and depth.

The article lacks transparency in its sourcing and methodology. It does not clearly identify where certain claims originate, such as the frequency of train crossings at Gisborne Airport or the specific instances of pricing at Istanbul Airport. The absence of direct quotes or links to primary sources makes it difficult for readers to verify the information independently. Greater transparency in the article's sourcing and the basis for its claims would significantly improve its reliability.
