My Buying Guides on Allegiant Personal Bag Dimensions
When I first started flying with Allegiant Air, I quickly realized how important it is to understand their personal bag dimensions. Having the right-sized bag can save you money and hassle at the airport. Here’s what I learned from my experience and what you should consider when choosing your personal item for Allegiant flights.
Understanding Allegiant’s Personal Bag Size Limits
Allegiant Air allows one free personal item per passenger, but it must fit within specific size limits. From my research and travel, the maximum dimensions for a personal bag are generally 18 x 14 x 8 inches (length x height x width). This includes handles and wheels, so I always measure my bag carefully before packing.
Why Dimensions Matter to Me
I’ve seen travelers get charged extra fees because their bag was even slightly too large. Allegiant is pretty strict about enforcing their size limits. Having a bag that fits comfortably under the seat in front of me means I can keep my essentials close and avoid the stress of gate-checking or paying for carry-on luggage.
Choosing the Right Bag Type
Based on Allegiant’s size restrictions, I recommend selecting a bag that’s compact but still roomy enough to carry your essentials. Some options I’ve found helpful include:
- Small backpacks that meet the 18 x 14 x 8 inch limit
- Tote bags or large purses with structured shapes
- Soft-sided duffels that can compress a little if needed
I avoid hard-shell suitcases as personal items because they tend to be bulky and might exceed the limits.
Tips for Measuring Your Personal Bag
To make sure my bag fits Allegiant’s guidelines, I use a tape measure and include every part of the bag:
- Measure the height from the base to the top, including handles
- Measure the width from side to side, including pockets
- Measure the depth from front to back, including wheels or protrusions
If my bag is close to the maximum size, I test packing it full and see if it still fits under an airplane seat or in a similar space at home.
What I Pack in My Allegiant Personal Bag
Since the size is limited, I focus on packing essentials only:
- Travel documents, wallet, phone, and chargers
- A small water bottle (empty before security)
- A book or tablet for entertainment
- Snacks for the flight
This keeps my bag light and easy to handle, which is key when you’re navigating busy airports.
Final Thoughts from My Experience
Understanding Allegiant’s personal bag dimensions has made my travels smoother and less stressful. I always double-check my bag’s size before each trip and choose one that’s practical and compliant. If you want to avoid extra fees and enjoy a hassle-free boarding process, paying attention to these dimensions is a must.
I hope my guide helps you pick the perfect personal bag for your next Allegiant flight! Safe travels!
