I fly very frequently with BusinessFirst, and with other, competing products of different carriers.
While BF is far and away my favorite way to travel, I have noticed these things:
-The 6" PTV is becoming standard for economy class, while a 7-8" unit is more or less the norm in business class on other carriers.
-At times, the IFE is scratchy with poor sound quality, or even inop
-the 55" pitch is now quite average, especially since DL, AA, and UA now all offer 60" pitch in their respective business class products.
-If BF is really supposed to be First-Class, as it claims to be, the intricate appointments of the UA First Suite, AA Flagship Suite, BA Suite, SQ First and others all feature things not found with CO, such as an extra-large PTV, video players, acoustic noise-canceling headphones, sleep suits, duvets, and a more extensive amenity kit.
I'm sure you get the idea by now, but I want you to also know that there is absolutely no comparison, anywhere in the world, to cabin crews of CO International (especially IAH-based, Southern Hospitality at its best!), and I have nothing but praise for the crews. Still the seat itself may need some upgrading to keep pace with the trendsetters in the industry.
