When was Delta Airlines founded? Have they always been regarded as the most luxurious airline since its inception?<|im_end|>
<|im_start|>assistant
Delta Air Lines was founded on March 2, 1925, in Macon, Georgia, United States under the name " Huff Daland Dusters". It is one of the oldest airlines in the world.

In terms of luxury, Delta Air Lines has not always been regarded as the most luxurious airline since its inception. In its early years, Delta was a small regional carrier serving the southeastern United States. Over time, the airline grew and expanded its network, but it did not become a major player in the airline industry until the mid-20th century.<|im_end|>
