Quote from: BassBoneFL on Jun 17, 2011, 09:12PMAs long as your case has a side that is 12in or less you should be OK on a 737. Also with Southwest, get in the "A" boarding group. Spend a couple extra bucks on their automatic early check in. If you're in the "A" group or early in the "B"s, there should still be plenty of room for your horn.
just measured my two cases:
Olds case measurements
35 x 13 x 9= 57 linear inches
King case measurements
37 x 11 x 9 = 57 linear inches

QuoteLinear inches is a term invented by the airline industry to measure baggage. The size of an item in linear inches is the sum of the length plus the width plus the height of the item. A 20-by-20-by-5-inch suitcase, a 1-by-11-by-4-inch painting and a 1-by-1-by-43-inch fishing rod are all the same size in terms of linear inches. Size restrictions are different for different classes of tickets and for different airlines, but the one constant is that airlines measure baggage in linear inches.

QuoteCarryon Baggage
Per TSA regulations, carryon items are limited to one bag plus one small, personal item.
Personal-type items include purses, briefcases, cameras, food containers, or laptops (case included).
Southwest Airlines limits carryon bag dimensions to 10 x 16 x 24 inches.
All Customers and Employees and their items are subject to a thorough, physical search.
The following items are not considered carryon bags or personal-type items and are not counted against the "one-bag plus one personal-type item" limit:
A child restraint device for a ticketed child with a reserved seat or when complimentary, available space exists.
Assistive/mobility devices for individuals with a disability. There is no limit to the number of assistive/mobility devices a Customer can bring onboard the aircraft.
Outer garments or other wearable articles of clothing.
Food for consumption during flight contained in disposable packaging.

QuoteMusical Instruments
If your instrument does not meet the sizing requirements for carryon items (10"x16"x24"), it will be handled as checked baggage provided you do not wish to purchase a seat for the instrument.
In the event you are traveling with a musical instrument that is larger than our sizing requirements for carryon luggage and is fragile in nature, you may purchase a seat for the instrument and carry it in the cabin under the following conditions:
The instrument must fit in the seat without blocking aircraft signage and be secured with a seatbelt.
The instrument must be placed in the first row and in a seat closer to the window than any other Customer in that row.
Reservations must be made and a ticket must be purchased at a charge no greater than the Child's Fare. Musical instruments cannot be transported in place of a free companion under any fare promotion.
Instruments that are transported in a soft-sided case or other packaging that is not strong enough to protect the instrument under normal baggage handling conditions will be conditionally accepted, which means that Southwest assumes no liability for any damage sustained to the item during transport.
so it looks like neither case would be ok? can any one measure their cases which have been allowed to be carried on and list it so I can compare measurements? The olds case looks much bigger to my eye than the king case. are they going to hassle me over 3 linear inches, would that difference prevent the case from fitting??
