No frills
A no-frills or no frills service or product is one for which the non-essential features have been removed to keep the price low. The use of the term "frills" refers to a style of fabric decoration. Something offered to customers for no additional charge may be designated as a "frill" - for example, free drinks on airline journeys, or a radio installed in a rental car. No-frills businesses operate on the principle that by removing luxurious additions, customers may be offered lower prices.
Common products and services for which no-frills brands exist include airlines, supermarkets, vacations and vehicles.
No-frills airlines
No-frills airlines are airlines that offer low fares but eliminate all non-essential services, such as complimentary food, in-flight entertainment systems, business-class seating etc. A no-frills airline will typically cut overhead by flying from more remote airports (with lower access charges) and by using a single type of aircraft. Aircraft cabin interiors may be fitted out with minimum comforts, dispensing with luxuries such as seat-back video screens, reclining seats and blinds; some airlines choose to carry advertising inside the cabin to increase revenue. Should meals be served, they must be paid for in full.
