I am designing a line of clothing for flight attendant uniforms. I want it to be based on functionality, comfort, yet aesthetically appealing. I was wondering what concerns i should keep in mind, or how flight attendants feel about their uniforms and what they would change or add.

Every other year I fly from the D.C area to Vilnius, Lithuaia to vist family. We fly June or in July- the most expensive time to fly transatlantic.

Would it be better for me to book for example since there are no direct flights to Vilnius, a flight to Copenhagen, and then seperately a flight from Copenhagen to Vilnius.
Instead of buying them together.

Its just when you buy together the airline will help you if you miss your flight due to a delay or something. But if you book seperate they most likely won’t help you, correct?
