I would suggest Abbot, if your company wears real wings, since they have the eyelets in the shirts. The shirts are of high quality, and I like the velcro pockets on the front. They have button sewn on the pocket closure, so it looks like a regular shirt, but it is much easier to retrieve your trip log/calculator/etc... They tailor the shirts to your liking. I wore their uniforms for several years at ASA, and then went to M&H when I changed companies. M&H seemed like K-Mart quality by comparison. Abbot is staffed by very nice people, and have even picked me up at the ATL terminal to come by their shop.

Second this recommendation about Abbott Uniforms. Good quality shirts.
