Every month, an airline printed advertisement, minus airline name and logo, is displayed for your guessing pleasure on Guess The Airline. The following is the answer to a previous game.
Once again, this was an advertisement published on a Time Magazine issue of 1990 in Montreal, Canada. Are you ready? Scroll down!

How to guess it?
The colors on the aircraft taking off were intentionally left intact. The aircraft type appears to be either a DC-9 or a Boeing 727. The text mentions the airline started domestic flights within the United States in 1980 or around that date and is inaugurating service from Philadelphia to Montreal in 1990. The slogan was also an important element. The text before the advertisement also mentioned that this airline went out of business in 1991. All those clues pointed to the original Midway Airlines.
