Spirit airlines is not going to get me down after yesterday's disaster with my Solo carry-on under the seat bag. I will be using the Travelpro Crew 8 Rolling Business Tote for my May transatlantic cruise. The dimensions come in at 13"x16"x8". Spirit requires 16"x14"x12". The tote also complies with Icelandair (the airline I will use on my return flight from London) carry-on requirements that are not to exceed 45 inches for (L+H+W). The bag is a little smaller then the Solo bag which I used for the one week cruise in January so the challenge to get the 36 unique outfits into that tiny space shall be greater. This quest shall be interesting to say the least!
