Would you choose 9 over 10 a breast seating? Question Title * 1. Would 10 a breast seating in Economy influence which airline you flew with? I would just choose the cheapest option whether 9 or 10 abreast I would only fly with an airline that offered 9 seats across as I know I will have more room and comfort I would fly 10 across but only if they offered more leg room than the airline offering 9 across My loyalty program influences who I fly with Done
