What happens if you don't select seats in web check-in?

what happens if you dont select seats in web check-in: 18% Risk

Understanding what happens if you dont select seats in web check-in protects travelers from unexpected boarding issues and family separation. Skipping this step leads to random seat placements by the airline system. Learn the risks of group splitting and discover how to manage your travel bookings effectively.

Here's what actually happens when you skip seat selection

not selecting seats at online check-in simply means the airline will assign you one automatically at no cost. This is standard practice, especially for basic economy tickets. However, you lose control over where you sit, which often means a middle seat or being separated from your travel companions.

The airlines system usually assigns your seat based on factors like ticket class and seat availability. Youll see the assigned seat number on your boarding pass once check-in is complete. Some airlines assign seats only a few hours before departure, so you might not know your spot until the last minute.

How auto-assignment works behind the scenes

When you check in online and dont pick a seat, the airlines system pulls from a pool of unselected seats. Passengers who paid for seat selection have already taken their preferred spots. The remaining seats - often middle seats, back-of-cabin rows, or less desirable locations - get distributed randomly. Airlines also prioritize elite status members, so their auto assign seats airline check-in tend to be better than those given to basic economy passengers.

Will you get separated from people you're traveling with?

This depends entirely on which airline youre flying. Most major carriers do a decent job keeping groups together without charging extra. On British Airways, 94% of passengers who didnt pay for seat selection still ended up seated with their travel companions. For easyJet ^[1], the figure was 93%, and for Jet2 it was 90%.

But some budget airlines make separation far more likely. Only 66% of Ryanair passengers who booked in groups without paying for seat selection ended up sitting together. For Wizz Air, that number drops to just 61%. Overall, about 18% of passengers who skip seat selection get separated from their traveling companions,^[4] though that percentage jumps significantly on certain carriers.

Theres no legal requirement for airlines to seat you next to family members, even young children. Most airlines will try, but theyre not obligated. The rule of thumb: if sitting together matters, especially for long flights, paying for seat selection is the only guarantee.

The financial side: How much are you actually saving?

Skipping seat selection can save you real money. Major US airlines charge anywhere from $10 to $150 just to select your seat in advance,^[5] depending on location and legroom. For a family of four, that could mean $100 or more each way - easily $200-400 round trip for the whole family. Many ask is seat selection mandatory for web check in, and the answer is usually no.

But heres the thing that surprises most travelers: nearly half of people who pay to sit together would have been seated together anyway. Youre paying for certainty, not necessity. ^[6]

The percentage of travelers paying for seat selection has actually increased. In 2024, 65% of consumers admitted to paying extra for seat selection at least once in the past year, up from 47% in 2023.^[7] Airlines have gotten good at making people feel like they have no choice.

The middle seat dilemma: What are your odds?

Auto-assigned seats are statistically more likely to be middle seats. Why? Because passengers who pay for seat selection grab aisle and window seats first. By the time you check in without paying, the remaining seats are predominantly middle seats, back-row seats, or seats with limited recline.

This doesnt mean youre guaranteed a middle seat - especially if you check in early. Some airlines release seats in batches, and early check-in can still get you a decent spot. But on popular routes or full flights, your odds of a middle seat increase significantly.

What about being "bumped" from an overbooked flight?

This is the fear that keeps many travelers up at night. The reality? Getting involuntarily bumped from a flight is extremely rare. Across 10 major US airlines, only about 0.47 passengers per 10,000 are involuntarily denied boarding. Thats ^[8] less than one in 20,000 passengers.

However, your airline choice matters. Frontier Airlines involuntarily bumps about 3.21 passengers per 10,000 travelers - 400% more than any other US carrier. ^[9] American Airlines follows at 0.6 per 10,000, then Spirit at 0.43 per 10,000. Delta and Allegiant had effectively zero involuntary bumps.

Having no seat assignment doesnt automatically make you the first to be bumped. Airlines use internal criteria including check-in time, fare class, and elite status. But its worth knowing what happens if you dont select seats in web check-in on certain budget carriers, as your risk is slightly higher. The odds are still very low overall.

How to find the "skip" button (even when airlines hide it)

Airlines have gotten sneaky about making the free option hard to find. Many use what regulators call dark patterns - design tricks that nudge you toward paying. You might see a seat map with most seats crossed out, suggesting you have no free options. Look carefully for small text like can I skip seat selection during check in or continue without selecting.

On some airlines, you have to click through multiple screens before the free option appears. Others make the continue button gray until you pick a paid seat - but clicking past it sometimes works. If youre truly stuck, completing check-in on the mobile app or website instead of the other often reveals the hidden skip option.

The "check-in chicken" strategy: Does late check-in get better seats?

Theres a growing trend called check-in chicken where passengers delay checking in as late as possible. The theory: airlines hold back some good seats for last-minute assignments, hoping to sell them first. When no one buys them, late check-in passengers get better spots.

Does it work? Sometimes. Some budget airlines reportedly release premium seats to non-paying passengers right before check-in closes. But the strategy carries real risk. If you check in too late and the flight is oversold, you could be the first bumped. And on full flights, you might end up with whatevers left - which is usually the worst seat on the plane.

When does skipping seat selection actually make sense?

Skipping seat selection is a smart move for solo travelers on short flights who dont care where they sit. Its also fine for budget-conscious travelers who prioritize saving money over seating preferences. For couples or families who can tolerate sitting apart, the consequences of skipping seat selection are manageable as the savings add up quickly.

When should you pay? Long-haul flights over 5 hours, when sitting together with children matters, or when you need specific accommodations like aisle access or extra legroom. Also, on airlines known for separating groups - Ryanair and Wizz Air being prime examples - paying for seat selection might be worth the cost.

• Low in absolute terms, but highest among US carriers

American Airlines (Moderate Risk)

• 0.60 passengers per 10,000
• 2.54 per 10,000
• Moderate but still uncommon

Delta Air Lines (Lowest Risk)

• 7.49 per 10,000 (highest voluntary rate)
• Extremely low for involuntary bumps

Sarah's family trip: $280 saved by skipping seat selection

Sarah, a mother of two from Chicago, booked a round-trip flight from Chicago to Orlando for spring break. The airline wanted $35 per person per flight to select seats together - that's $280 total for the family of four round trip. She was nervous about being separated from her young kids.

She decided to skip seat selection and check in exactly 24 hours before departure. At check-in, the system assigned all four seats together in the back of the plane. Her kids sat next to her the entire flight. No issues, no stress, and $280 still in her pocket.

Sarah learned that on major US carriers like United and Delta, groups are usually seated together even without paying. The airline's algorithm prioritizes keeping families together. The only downside? They sat near the restrooms, but for a 2.5-hour flight, it was worth the savings.
