Choosing among trolley bags in a large size for a week long family trip comes down to two sums, the three listed edges added together and the empty weight taken off the airline allowance. Akasa Air and SpiceJet both state a limit of 158 cm for length, width and height combined on a domestic checked bag, and two of the three biggest bags here list totals above it.
A parent packing for two adults and one or two children is often worried about overweight charges, and a bigger bag does not mean more can go in. The four bags below run from a medium soft bag to a 75 cm hard shell with an expander, and each is compared on figures from its own brand page.
Adding up length, width and height
Akasa Air lists one checked piece per guest, with length, width and height not above the combined limit. SpiceJet states the same total for domestic flights, and its page gives no rule on hard or soft bags.
Added from the listed figures, the Safari Select Panorama large comes to 156 cm, the VIP ALFA large to 160 cm, the Nasher Miles Krabi to 164.5 cm and the American Tourister Fornax to 138.5 cm. These sums are our arithmetic, not brand claims.
On paper, then, two of the three biggest bags sit above the airline total. Against 158 cm, the Safari has 2 cm in hand, the Fornax has 19.5 cm, the VIP is 2 cm over and the Krabi is 6.5 cm over.
Krabi figures are listed as width 38, height 75 and length 51.5, and its page does not say whether they include the expander section. A reader who adds the expander to the sum could land higher still.
Safari says its expander gives up to 25% more packing capacity, and the VIP ALFA page lists an expander without giving a capacity or a size when it is extended. The Safari total is calculated before the expander is used, which leaves it little margin.
IndiGo’s baggage page lists one piece for domestic check in at 20 kg, worded per person. It also shows a size figure, but the layout does not make clear which bag that figure applies to.
Samsonite India helps with naming. Its size chart gives a medium checked bag as 61 x 41 x 30 and a large checked bag as 71 x 46 x 30, with the axes unlabelled. The page adds that longer journeys or more stops call for bigger bags, and it gives no trip lengths.
A bag of the Krabi height sits above that large size. By the same addition, that large size comes to 147 cm and the extra large size to 168 cm, which is above the airline total on paper.
What the empty weight leaves
Empty weights on the pages are 3.5 kg for the Safari, 4.1 kg for the VIP and 4.4 kg for the Krabi. The Fornax page gives only a range of 3 to 4 kg.
On the 15 kg that Akasa Air and SpiceJet list for one piece, that leaves roughly 11.5 kg of contents with the Safari, 10.9 kg with the VIP and 10.6 kg with the Krabi. The Fornax leaves between 11 and 12 kg, since its weight is a range.
IndiGo’s higher allowance leaves 16.5 kg with the Safari, 15.9 kg with the VIP and 15.6 kg with the Krabi. All of these are subtractions from listed figures. A family that packs to the limit reaches the allowance sooner with the Krabi than with the Safari, since the Krabi weighs 0.9 kg more empty.
Capacity per kilogram of empty weight gives a second view. Using the listed figures, the Safari holds about 41 L for each kg of bag, the Krabi about 33 L and the VIP about 25 L, while the Fornax comes to between 17 and 22 L because its weight is a range. These ratios are our arithmetic.
Total litres do not follow empty weight. The Krabi lists 146 L and the Safari 145 L, while the VIP lists 102 L and the Fornax 67.5 L. The VIP page does not give a capacity with its expander extended.
Hard shell or soft for a big bag
Travelpro says hard side luggage offers maximum protection for the contents and can withstand rough baggage handling. It calls polypropylene the lightest of the hard materials but not as rigid as polycarbonate, and says polycarbonate resists cracks, scratches and impact while being more difficult to repair.
Nasher Miles shows ten products on the first page of its large trolley bags collection, and all of them are hard sided bags of 75 cm. One of them, the Denver, is polycarbonate at 75 x 51.5 x 28 cm and 109 L, with a 2 year shell warranty, a year shorter than the Krabi.
Safari also sells a polycarbonate Hue large, listed at 77 x 55 x 32 cm, 118 L and 6.1 kg, which adds to 164 cm. That empty weight is the highest of any bag read for this guide.
Soft bags carry the lighter empty weights here. The VIP ALFA page is not consistent about its shell, since the text calls it soft while an icon on the same page points to a hard shell.
Bag by bag
The Nasher Miles Krabi Expander is a polypropylene hard shell of 75 x 51.5 x 38 cm, listed with height, length and width in that order, so the 75 in its name is the height. It holds 146 L, the biggest listed capacity of the four.
VIP sells the ALFA Shield Safe Large, a soft polyester bag with an expander. It measures 79 x 48 x 33 cm, holds 102 L and rolls on 360 degree spinner wheels.
Safari lists its Select Panorama large as polyester that its page says resists water and dust, at 78 x 49 x 29 cm and 145 L. The same page lists a cabin size of 55 x 32 x 24 cm at 2.20 kg and 43 L, and a medium of 67 x 41 x 26 cm at 2.90 kg and 82 L, so the large is the top of a three size range. Its title tag and meta text disagree on the largest size, 78 cm in one place and 79 cm in the other.
From American Tourister comes the Fornax Spinner Medium, a soft polyester trolley bag of 66 cm, listed as 42 x 66 x 30.5 cm in length, height and width. It holds 67.5 L, and the page mentions no expander. The brand describes it as a soft trolley bag.
At that length it is only just over the 65 cm mark used here for a large check in bag, and it is the smallest of the four by capacity.
Locks, wheels and warranty terms
The Krabi has a number combination lock described as TSA friendly. Its spec lists 8 wheels while the description says four, so the page contradicts itself on wheel count.
VIP fits a 3 dial flushed combination lock, and its page lists 8 spinner wheels. The Safari has a TSA approved lock and dual wheels, and the Fornax has double wheels and a TSA lock named in its description.
On warranties, the Krabi page gives three years for the shell and one for accessories, along with 7 day returns. The Fornax page lists a 3 year international warranty.
VIP gives two different terms on one page, a period in its features text and a lifetime badge, so neither is stated as fact here. Its rain cover field also shows a spreadsheet error, and no water resistance claim is repeated. The Safari page states no warranty period in text.
American Tourister warranty terms, read from its Airconic page and described there as the brand terms, cover only manufacturing defects and exclude airline transport damage and abrasion. Nasher Miles warranty text says wear and tear and scratches are not covered.
Which bag suits which family
The Krabi suits a packer who wants the biggest listed capacity on a hard shell with an expander. Its listed total is the highest of the four and its page is inconsistent on wheels, which a buyer would weigh against that capacity.
For a family that wants the lightest empty weight in a 78 cm bag, the Safari fits, and of the three biggest bags it alone sums to less than the airline figure. Its page gives no warranty period in text.
A soft expandable bag with a lock built in is what the VIP ALFA offers, and families who prefer that design would note that its listed total is just above the airline figure and that its page conflicts on warranty and shell type.
The Fornax suits a family that prefers a soft bag whose total leaves a wide margin under the airline figure. Its weight is listed only as a range, so the packing allowance it leaves is approximate.
A few of these pages gave no sign in November 2026 that the bag could be ordered, the Safari Panorama among them.
