If you have elite status, you may have even more options. United Airlines, for instance, offers a same-day confirmation service on select flights for all passengers with elite status—that means they can make a guaranteed switch to an earlier flight in the same cabin class at no charge, without paying a difference in fare.
Contact your carrier’s customer service
When in doubt, call the carrier’s customer service line and ask an agent to check how full the flight is. It might not be the most convenient option, but it will yield an answer. If you dread the idea of waiting on hold, many airlines offer customer service chat features. Southwest Airlines, United, and Delta’s mobile apps all have live chat options, and JetBlue agents are available through Apple Business Chat. United also has a text option for customer service help. Passengers can text “UNITED” to 32050, and an airline representative will get in touch when it’s your turn in the queue—no waiting on hold required.
Other strategies to avoid crowded flights
Aside from checking how full your flight is in advance, there are a few other tactics travelers can use to potentially avoid crowded planes. If an empty plane is a priority of yours, be strategic about the day of the week, time of year, and time of day you plan to travel.
January is usually the least busy month for air travel overall, according to data from Expedia. On the flip side, flights in August are among the fullest all year.
On average, Tuesday is the quietest day of the week to fly, per Expedia. Flying on that day “may mean you have less need to worry about reclining on someone or fighting for overhead bin space,” says Expedia’s 2025 air travel report. “While it may not always be the cheapest day to travel, it’s the best choice for those seeking a more relaxed trip.”
Sundays are one of the most crowded and stressful days to fly, according to global feedback from more than 9 million travelers collected by the company HappyOrNot, which operates those ubiquitous kiosks with smiley face/frowning face buttons at airports in order to conduct spot checks on traveler satisfaction.
As for the best time of day to avoid a crowded plane? Aim for earlier morning departures, which usually mean fewer travelers and a less stressful experience, per the HappyOrNot report. Specifically, departures at 4 a.m. and between 7 a.m. and 8 a.m. have the fewest passengers and highest rate of traveler satisfaction (84.8%), according to HappyOrNot’s data, which was gathered in the first quarter of 2025. The company’s report sums it up thusly: “For those looking to minimize stress and maximize ease, flying earlier in the day—and avoiding Sunday departures—may help ensure a smoother airport experience.”
