I would never touch TCD with a barege pole agian. It is not the issue of delays, whch is bad enough, but as many poeple say, these can happen to any airline, although TCD does seem to get more. My main gripe is the way we were treated, or the total lack of treatment during the delay, we were lied to (in sequence; rep is on the way, rep has been delayed, rep will be there in the morning), total lack of any consideration, rude staff, and a total could not care less attitude.
They are cheaper, and if this is the only way you can do it then it may be worth the risk, but today there are other companies that can beat the price sometimes so it is worth shopping around.
