When choosing an airline, I always look at the company's reputation and reviews from other passengers. Reliability and punctuality are key factors, because this determines how comfortable your flight will be. It is also important to consider the terms of ticket refunds and additional services, such as food or baggage. I even always have jetblue customer service email with me. For me personally, good service and safety are in the first place, so I advise you to carefully approach the choice of an airline.
