Not too long ago, airline travel was normally a very enjoyable part of a vacation.
Now, it's a total ordeal that must be endured to get to the vacation resort.
The simple answer is to take your business to another airline or to avoid air travel altogether if travelling on vacation.
Unfortunately, it seems that there is a downward spiral with regard to customer service, unless you can afford to pay for "First Class" or its equivalent. Some staff seem to hide behind "the regulations" as an excuse to provide a sub-standard service.
