I had a reservation for wednesday evening on Easy Jet flight back to Brussels. Due to a problem on railway network (bomb from WWII near railway station in Schönefeld we arrived at the check in exactly 32 min before departure time of the flight. We were of course not alone in this situation because many people were blocked in the trains between Berlin City and Schönefeld. But ... check in for Easy Jet flights closes officially 40 min before departure. So we were around 30 people (yes, you read it correctly, THIRTY !!) to be simply rejected from the flight and rebooked on the same flight 24 hours later ! With of course all the consequences : one more day in Berlin, costs for hotel, food ... and last but not least 60 EUR per person for Easy Jet for modification of the reservation ! Jackpot, guys !!
According to some smartasses around here however, you simply should have booked at least 3 tickets on different flights the day of your departure, checked in for all 3 and then have aimed for the first one (otherwise there's obviously no reduncandy in having booked multiple tickets), thus loosing out on more than half of your useful day in Berlin, only to have some sort of self-invented flexibility in case something does go wrong: definitely great efficiency and excellent time management, notably in all those cases where things do not go wrong...
BTW, you do notice you were quite lucky U2 still had 30 open seats on their very next flight (albeit the day after) and you thus had to stay just 1 extra night in Berlin at your own expenses, do you?
Accomodating 30 pax last minute can be quite a challenge and Easyjet might as well offered you a place on a flight of theirs lightyears away, in which case you'd be really screwed!
Remember LCCs are not going to help you onto another airlines' flight to BRU, nor will they offer you an alternative routing like for instance SXF-GVA-BRU (even if it is on their own airline!), unless you'd book those 2 legs yourself last minute, all while throwing away your SXF-BRU ticket! Oh, and mind you: you might just end up in the same situation in GVA a couple of hours later, as LCCs do not guarantee any connections!
That's exactly what corporate customers want to avoid: they want to know that even if they miss out on a seat on the flight from TXL to BRU (one of the 6 daily), they can always count on a swift rerouting through for instance the hubs of FRA or MUC, thus still making it back to the office the very same day (albeit with delay) and thus not having to worry about any of their meetings the very next day: that's what they are willing to pay a premium for.
That premium is not so much to be seen as an insurance against all the unknown extra costs of some extra hotelnight(s) or a rebooking fee that may be charged to them, but rather as an insurance against a potentially massive time loss (a full working day or more even!) as well as against serious work schedule problems for a whole bunch of people they work with.
And they absolutely want this kind of insurance not because they doubt the punctuality or the reliability of a LCC as such, but because they know very well their own work planning is quite challenging to start the day with and will most likely evolve quite dynamically so to say, meaing they will create their own delays as the day goes by.
That's how it works and what it is all about: those who think frequent flyers pay a premium for the fantastic tuna salad they will get on board have an extremely naive view of network carriers as well as their frequent flyers, just as has been demonstrated here today once again.
