- Tested against Singapore Airlines' 115 cm total limit, a standard US carry-on of 22 × 14 × 9 in (55.9 × 35.6 × 22.9 cm) fits, but with only 0.7 cm (0.3 in) to spare on the total size.
- On Singapore Airlines, a typical European cabin case of 55 × 40 × 20 cm (21.7 × 15.7 × 7.9 in) fits exactly at the limit on the total size (limit: 115 cm total).

- Of 57 verified airlines with a published cabin weight limit, 34 allow more than Singapore Airlines' 7 kg (15.4 lb) for the cabin bag and 0 allow less.
- Singapore Airlines publishes only a total for the cabin bag: length + width + height up to 115 cm, so the proportions of the bag are free.
- Exceptions noted on the official Singapore Airlines page: “Suites — First Class — Business Class — 2 pieces — Up to 7kg each — Sum of length, width and height of each piece should not exceed 115cm.”
Singapore Airlines personal item: what fits under the seat

- Filled as a box, Singapore Airlines' 40×30×10 cm personal item holds about 12 litres, below the median of 18 L across the 56 airlines that publish three personal item sides.
- Against the 5 airlines from Southeast Asia that publish a personal item size (average 80.2 cm in total), Singapore Airlines allows 80 cm, more than 25% of them.
- A soft 40 × 30 × 20 cm (15.7 × 11.8 × 7.9 in) under-seat bag is 10 cm (3.9 in) too big on the depth against Singapore Airlines' 40×30×10 cm personal item limit.
- With 80 cm in total, the Singapore Airlines personal item is bigger than 4 and smaller than 48 of the 57 verified airlines that publish a personal item size.
