According to the organisation's data, and reported by Publituris, the Portuguese airports that present the lowest rates of disruption are: Porto and Faro do Pico with 72% of flights without disruption, while, on the opposite side, the airports of Lisbon, Horta and Ponta Delgada are those which present the worst options, with 52%, 64% and 68% of flights suffering some type of disruption, respectively.

Another piece of advice is to favour airlines that have fewer flights with disruptions (and that travel to the selected location). In Portugal, during the summer of 2023, the most reliable airlines in terms of punctuality were, in this order: Eurowings with 97% of flights not suffering any constraints; Binter Canarias with 88% of flights undisturbed; and, finally, Jet2.com with 82% of flights operating without problems. TAP recorded some type of disruption on 44% of flights.

Choosing the best days and times to fly must also be taken into account. Mondays are considered one of the worst days to fly, as airlines tend to experience a higher rate of cancellations compared to other days. Furthermore, the high demand that occurs on weekends – from Friday to Sunday – can mean greater difficulties for travellers. Therefore, Tuesdays and Wednesdays, with lower demand, are generally the best days to fly. At the same time, AirHelp recommends flying early in the morning because, as the day progresses, there is a 'snowball effect' which can make delays and problems worse as the day progresses.

According to data from AirHelp, between June and September 2023, in Portugal, more than 13 million passengers travelled by plane, of which more than five million travellers (approximately 38%) suffered some type of disruption on their flight (delay or cancellation). Of these five million, more than 287 thousand passengers were entitled to compensation (which can reach up to 600 euros per passenger).
