A paragraph about a complaint on Iberia airports, but some sentences doesn't make much sense to me. Si Iberia dispusiera de aeropuertos con terminales en exclusiva; si el pasaje presentara a la hora del embarque y no entretuviera en el duty free; si las agencias de viajes no vendieran conexiones entre vuelos con menos de una hora de intermedio; si la gente apagara sus móviles a bordo; si se estuviera pendiente de la megafonía y de las pantallas de información; si se guardaran las etiquetas del equipaje; si se confirmaran las plazas con una semana de antelación; si no se formaran colas para preguntar lo obvio(o lo que se puede mirar en los paneles informativos); si los afectados por problemas no se pusieran tan bravos...; si todo esto ocurriera, otro gallo nos cantaría. For the above paragraph, some sentences doesn't make much sense to me, and if you could translate the whole paragraph for me, that will be GREATLY appreciated. Thanks in advance!If Iberia had their own chek in desks ; if tickets were presented at the due time instead of being distracted at the duty free shop; if travel agents did not to sell connections between flights in less than an hour interval; if people turned off their phones on board; if the passengers were paying attention to calls on loudpeakers and information screens; if luggage tags were kept ; if the seats were confirmed a week in advance; if travellers did not form queues to ask the obvious (or what they can see at the information panels); if thsoe with a complain did not get so upset ...; if these things did not happen , things would be much better.I got the above answer from a friend, and I followed it to straighten out the entire paragraph, now it's more clear to me. But if you have a better version, pls do leave your replies here. Thanks
