It sure is strange not hearing any planes. My coworkers were scrambling getting back to UK on Thursday. Most of the consultants travel back and forth Monday and Thursday. The ones booked on Eurostar were lucky. One coworker had to pay for a full business seat on Eurostar; another was not so lucky as trains were already sold out.
Now, it is appearing that airports may not be back open by Monday morning. Those that did make it to UK may wish that they had just spent the weekend in Brussels.
We are flying to Krakow in two weeks; I hope the volcano is finished by then. I really don't want to get stranded in Poland or have to spend an extra day getting home by train.
