Hi,
my list of airlines in order of preference:
TAP (have flown with them only once - FRA-LIS-OPO and the return OPO-LIS-FRA, on the way back the check-in agent offered to be rebook us on an earlier flight from OPO to LIS to avoid the short transfer time at LIS on her own initiative and for free…that’s what I call costumer service!)
Air Berlin (generally good service on short routes, have flown them several times within Germany, they have IFE on all A320 Series Aircraft and some B737 even on very short routes and offer snacks)
Tuifly (good service/food, friendly crew and rather cheap flights - their main problem is that they squeze 189 Seats into a 738, which results in insufficient space…)
Aegean Airlines (good airline, mostly on time and good service - anyway the food is not really my taste…)
Lufthansa (while they are a big airline their service is not good compared to f.e. Air Berlin, no IFE at all on short routes and sometimes rather rude crews)
Ryanair (when you book a cheap flight you often end up paying more than for a flight with a full service carrier and no service at all…anyway, I might book on their flights when doing a daytrip or so)
