Соответствие цены и качества полета. Нормальное обслуживание на борту. Есть напитки холодные(вода, соки) и горячие(чай, кофе). Можно подкрепиться во время перелета бесплатной шоколадкой или хрустиками.
I've been flying with Fly Niki for two years and I am quite satisfied with their services in general. Except for a short delay due to poor weather conditions I haven't experienced any troubles during my trips. The crew is professional and they provide good comfort to the passengers (the even offer free magazines and newspapers but only in German language). Even if there are cheaper low cost airlines, I think that Fly Niki is a trustworthy company and their services are a good value for money.
Book well in advance: The cheapest tickets sell first. The policy of lowcost airlines is to sell cheap tickets at first and to gradually increase the price as tickets are bought. Usually, if you buy your ticket 2-3 months in advance, you will probably get the best price.
