Confusion often arises when travellers try to determine if their backpack can be used as a carry-on. With varying airline policies and unclear definitions, it’s easy to get overwhelmed.
Not knowing whether your backpack qualifies as a carry-on could lead to last-minute hassles, extra fees, or the inconvenience of having to check it in.
In this guide we clarify whether a backpack can be considered a carry-on, covering key factors like size, airline rules, and tips for choosing the right backpack for your travels.
What Qualifies as a Carry-On?
A carry-on is a piece of luggage that passengers can bring onboard and store in the overhead compartment. Typically, carry-on items include small suitcases, duffel bags, and in some cases, backpacks.
Airlines generally set specific size restrictions for carry-on luggage, usually around 22 x 14 x 9 inches (56 x 36 x 23 cm), including handles and wheels. These regulations vary slightly depending on the airline, so it’s crucial to check before you fly.
Additionally, carry-on weight limits may be enforced, with some airlines imposing stricter limits than others.
Common Items Included as Carry-Ons:
- Small rolling suitcases, like underseat suitcases or carry-on suitcases
- Travel backpacks
- Duffel bags
Important Considerations
- Airline Size Limits: Size dimensions can vary slightly from one airline to another. Knowing the specific requirements for your carrier can help avoid unexpected fees.
- Overhead Bin Storage: Carry-ons are typically stowed in the overhead bin, so they need to fit comfortably within these dimensions.
- Weight Restrictions: Some airlines have weight limits for carry-on items, often ranging between 7-10 kg (15-22 lbs), although this can differ.
Understanding these factors is key to determining whether your backpack qualifies as a carry-on or if it’s better suited as a personal item.
Backpacks: Carry-On vs. Personal Item
The key difference between a carry-on and a personal item lies in their size and intended placement on the plane. A carry-on is typically larger and is stored in the overhead bin, while a personal item is smaller and meant to fit under the seat in front of you.
Airlines usually allow passengers to bring both a carry-on and a personal item, but the classification of a backpack can be tricky. Whether your backpack is treated as a carry-on or a personal item often depends on its size and the airline’s specific guidelines.
Common Airline Guidelines
- Size Limits: Most airlines consider a backpack as a carry-on if it meets the size dimensions of around 22 x 14 x 9 inches. However, if it’s smaller (like a daypack), it could be classified as a personal item.
- Number of Bags Allowed: Airlines typically allow one carry-on and one personal item per passenger. If your backpack is your carry-on, you may need to pack an additional small item like a travel waistbag or laptop case as your personal item.
- Airline Examples: For instance, low-cost carriers often have stricter rules and may treat any sizable backpack as a carry-on, while full-service airlines may be more lenient in allowing certain backpacks as personal items.
Understanding these distinctions is crucial to avoid issues at check-in and to make sure you can bring everything you need onboard without extra fees.
Factors to Consider When Using a Backpack as a Carry-On
Size and Dimensions For Meeting Carry-On Limits
The most important factor is whether your backpack fits within the carry-on size limits set by airlines. Generally, a carry-on should not exceed 22 x 14 x 9 inches (56 x 36 x 23 cm), but the dimensions vary between carriers. Ensure that your backpack is within these limits, including when packed fully.
Pros & Cons of Using a Backpack
Using a backpack as your primary carry-on offers several advantages, including ease of carrying, versatility, and hands-free travel. However, drawbacks include limited structured space and potential discomfort if the backpack is heavy. Backpacks are often more flexible in squeezing into tight overhead bin spaces or under seats, but they may lack the compartmentalised organisation that suitcases provide.
Comparing Backpacks with Suitcases or Duffel Bags
When choosing between a backpack, suitcase, or duffel bag as a carry-on, consider your travel needs. Backpacks are ideal for those who prioritise mobility and flexibility, especially in crowded spaces or when travelling by public transport. Similarly, carry on tote bags offer the same advantages in a different style and design.
Suitcases offer better organisation and structure but can be cumbersome. Duffel bags are versatile and can expand to fit more items but might not offer the same ergonomic comfort as backpacks.
Airline-Specific Policies
When considering using a backpack as a carry-on, it's important to recognise that airline policies vary significantly. While most carriers adhere to standard size guidelines, their interpretations of what qualifies as a carry-on versus a personal item can differ.
Overview of Airline Rules
- Low-Cost Carriers: Budget airlines like Ryanair and Spirit tend to be stricter, often allowing only one small personal item unless you pay extra for carry-on privileges. Larger backpacks are generally treated as carry-ons.
- Full-Service Airlines: Airlines such as Delta, American Airlines, and Qantas usually allow a backpack as either a carry-on or personal item, depending on its size. If it fits under the seat, it’s typically classified as a personal item.
Examples of Popular Airlines
- United Airlines: Allows one carry-on bag plus a personal item, with standard carry-on size limits. A small backpack can qualify as a personal item.
- Southwest Airlines: Has generous carry-on and personal item allowances. A moderately-sized backpack can often be used as a carry-on, with an additional smaller item permitted.
Understanding specific airline policies helps ensure that your backpack is classified appropriately and that you avoid unexpected fees or complications during boarding. Always verify the dimensions and regulations for your chosen airline before travelling.
