When check-in opens, what it costs to print at the airport, and the small mistakes that cost LCC passengers their seats.
When online check-in opens
Most low-cost carriers open online check-in 24 to 48 hours before departure. Some open earlier for paid seat-selection holders or loyalty members. Typical opening windows: Ryanair 60 days (with a paid seat) or 24 hours (without); easyJet 30 days; Wizz Air 30 days for members, 48 hours otherwise; Spirit 24 hours; Frontier 24 hours; AirAsia 14 days for paid seats, 14 days standard.
Set a calendar reminder for the moment your window opens. Late check-ins are the first denied-boarding candidates on oversold flights, even if you arrive at the gate on time.
The airport check-in fee trap
Several low-cost carriers charge a fee if you have not checked in online before arriving at the airport. Ryanair currently charges EUR 55 to print a boarding pass at the desk if you did not check in online. Wizz Air charges EUR 35. Spirit charges USD 25 for an airport-printed boarding pass. These are punitive and difficult to dispute.
Always check in online and either save the mobile boarding pass to your phone's wallet app or screenshot it. Both work, the screenshot is the safer fallback if airport Wi-Fi is patchy.
Bag-drop closes earlier than the printed cutoff
A boarding cutoff of 'gate closes 20 minutes before departure' often hides an earlier bag-drop cutoff: 40 minutes before on Ryanair and Wizz, 45 minutes before on most US LCCs. If you check a bag, plan to be at the bag-drop counter at least 60 minutes before departure on a short-haul flight, 90 on long-haul. Missing bag-drop is the single most common reason budget passengers miss otherwise on-time flights.
Document checks for international flights
Many LCCs require an in-person passport check at the desk for non-EU/non-US international flights, even if you have a mobile boarding pass. The desk often closes 60 minutes before departure with no exceptions. Check the airline-specific rule for your route and queue early.
Seat selection, pay or skip
On a flight under 2 hours, skipping paid seat selection costs you almost nothing, you will be assigned a free seat at check-in, often a middle. On flights over 3 hours, paying for seat selection is usually worth it for an aisle or window. On overnight flights, always pay; the rest is misery.
Some carriers (Ryanair, Spirit) deliberately split family bookings if you do not pay for seats. Always pay for a seat for any passenger under 12 to avoid the gate-agent shuffle.
Mobile boarding pass gotchas
A few destinations (Brazil, parts of India, several airports in China) still require a printed boarding pass for security or boarding. Check the route requirement. Dimensions for QR-code scanners can be picky on cracked phone screens, bring a print backup or be ready to brighten your screen to 100%.
Loyalty programmes are worth signing up for even for one trip
Many LCC loyalty programmes are free and waive the airport check-in fee, give faster customer service, and offer occasional change-fee discounts. Sign up before booking to get the credit on your first flight. Wizz Discount Club, easyJet Plus, Spirit Saver$ Club, and Allegiant Allways Rewards each have different value propositions; most break even after 2–3 trips per year.
